Understanding the Errors

The error logs indicate several critical issues preventing MoviePilot from successfully retrieving and installing plugins. These issues range from network connectivity problems to GitHub-related request failures. Let's break down the errors:

  1. GitHub Request Failures: The most prominent errors are related to the inability to connect to GitHub to retrieve plugin packages. This is indicated by messages such as:

    • HTTPSConnectionPool(host='raw.githubusercontent.com', port=443): Max retries exceeded with url: ... (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x...>: Failed to establish a new connection: [Errno 101] Network is unreachable'))
    • [GitHub] 所有策略均请求失败，URL: ...，请检查网络连接或 GitHub 配置 (All strategies failed for URL: ..., please check network connection or GitHub configuration)
    • These errors suggest that the MoviePilot application, running within a Docker container, cannot establish a connection to GitHub. The Errno 101 typically indicates a network unreachable error.

  2. Plugin Repository Retrieval Failures: The subsequent warnings highlight the failure to fetch plugin libraries from specific GitHub repositories:

    • 获取v2插件库失败：https://github.com/madrays/MoviePilot-Plugins，请检查 GitHub 网络连接 (Failed to get v2 plugin library: https://github.com/madrays/MoviePilot-Plugins, please check GitHub network connection)
    • 获取插件库失败：https://github.com/justzerock/MoviePilot-Plugins，请检查 GitHub 网络连接 (Failed to get plugin library: https://github.com/justzerock/MoviePilot-Plugins, please check GitHub network connection)
    • These warnings confirm that the application cannot access the necessary plugin repositories, which are crucial for installing and updating plugins.

  3. TheMovieDb (TMDb) Connection Errors: Another significant error is the inability to connect to TheMovieDb API:

    • 无法连接TheMovieDb，请检查网络连接！ (Unable to connect to TheMovieDb, please check network connection!)
    • This error indicates that MoviePilot cannot access TMDb, which is often used for fetching movie metadata, posters, and other related information. This can impact various functionalities within MoviePilot.

  4. Timeout Errors: Additionally, there are timeout errors reported when trying to access certain GitHub repositories:

    • HTTPSConnectionPool(host='raw.githubusercontent.com', port=443): Read timed out. (read timeout=60)
    • This suggests that the application is attempting to connect to GitHub, but the connection is timing out after 60 seconds, indicating potential network latency or connectivity issues.

These errors collectively point to underlying issues with network configuration, DNS resolution, or the application's ability to access external resources. Addressing these errors requires a systematic approach, which we will outline in the troubleshooting steps below. Ensuring these connections are stable is vital for the seamless operation of MoviePilot and its plugins.

Troubleshooting Steps

To resolve the MoviePilot plugin installation errors and ensure the application can properly retrieve plugins and connect to external services, follow these detailed troubleshooting steps:

1. Verify Network Connectivity

The first and most crucial step is to verify that the Docker container running MoviePilot has proper network connectivity. Since the errors indicate that the application cannot reach external resources like GitHub and TheMovieDb, confirming network access is essential. Here’s how to do it:

  • Check Basic Internet Access: Inside the Docker container, use basic network utilities to check internet connectivity. You can use commands like ping, traceroute, or curl to test external connections. For example:

    docker exec -it <container_id> bash
ping google.com
curl https://www.google.com

    Replace <container_id> with the actual ID of your MoviePilot Docker container. If the ping command fails or curl returns an error, it indicates a problem with internet access within the container.

  • Verify DNS Resolution: Ensure that the container can resolve domain names correctly. Use the nslookup command to check if DNS resolution is working:

    nslookup github.com

    If DNS resolution fails, the container might be using an incorrect DNS server. You may need to configure the container to use a valid DNS server, such as Google's public DNS (8.8.8.8) or Cloudflare's (1.1.1.1).

  • Inspect Docker Network Configuration: Docker uses its own networking system, and sometimes the default network configuration may not suit your environment. Use the docker network inspect command to examine the network settings:

    docker network inspect <network_name>

    Replace <network_name> with the name of the Docker network your container is connected to. Look for issues such as incorrect subnet configurations or missing gateway settings. You might need to create a custom Docker network or adjust the existing one to ensure proper connectivity.

2. Check Docker Container's Network Mode

The network mode in which your Docker container is running can significantly impact its ability to access the network. There are several network modes, but the most common are bridge, host, and none. Ensure that the network mode is correctly configured for your environment:

  • Bridge Mode: This is the default mode and often the source of network issues. In bridge mode, the container gets its own IP address within a Docker-specific subnet and communicates with the host and external networks via NAT (Network Address Translation). This can sometimes lead to connectivity problems if not configured correctly.

  • Host Mode: In host mode, the container shares the host's network stack, effectively giving it the same network access as the host. This can resolve many connectivity issues but might have security implications. If you are facing network problems, try running the container in host mode to see if it resolves the issue:

    docker run --net=host ...

  • None Mode: This mode provides no network access to the container, which is not suitable for MoviePilot, as it requires network access to fetch plugins and movie data.

3. Proxy Configuration

If your network uses a proxy server, MoviePilot and the Docker container must be configured to use it. Without proper proxy settings, the application will fail to connect to external resources. Here’s how to configure proxy settings:

  • Set Environment Variables: Docker containers can be configured to use a proxy by setting environment variables. Common proxy-related environment variables include HTTP_PROXY, HTTPS_PROXY, and NO_PROXY. You can set these variables when running the Docker container:

    docker run -e HTTP_PROXY=http://<proxy_host>:<proxy_port> \
           -e HTTPS_PROXY=http://<proxy_host>:<proxy_port> \
           -e NO_PROXY=<internal_networks> ...

    Replace <proxy_host> and <proxy_port> with your proxy server’s address and port. The NO_PROXY variable is used to specify internal networks or hosts that should be accessed directly, bypassing the proxy.

  • Configure MoviePilot: MoviePilot itself might have settings to configure proxy servers. Check the application’s documentation or settings panel to see if there are specific proxy configuration options. Ensure these settings match your network’s proxy requirements.

4. GitHub Connectivity Issues

Even if general internet connectivity is working, there might be specific issues related to connecting to GitHub. Here are some steps to troubleshoot GitHub connectivity:

  • Check GitHub Status: Sometimes, GitHub might be experiencing outages or other issues that prevent access. Visit the GitHub Status page (https://www.githubstatus.com/) to check if there are any ongoing incidents.

  • Firewall Rules: Ensure that your firewall is not blocking connections to GitHub. GitHub uses HTTPS on port 443, so make sure this port is open for outbound traffic. If you are using a firewall within your Docker environment, adjust the rules accordingly.

  • Rate Limiting: GitHub has rate limits for API requests, and if you exceed these limits, you might experience connection issues. While this is less likely to be the primary cause, it’s worth considering if you are making frequent requests to GitHub. Review GitHub’s rate limit documentation for more information.

5. TheMovieDb (TMDb) Connectivity

Similar to GitHub, issues connecting to TheMovieDb can stem from network problems or TMDb outages. Follow these steps to troubleshoot:

  • Verify TMDb Status: Check TheMovieDb’s status page or other means of monitoring its service availability. If TMDb is down, there’s nothing you can do but wait for it to come back online.

  • API Key: Ensure that your MoviePilot installation is using a valid TMDb API key. An invalid or missing API key will prevent the application from accessing TMDb’s services. Check MoviePilot’s settings to confirm the API key is correctly configured.

  • Firewall and Network Issues: Similar to GitHub, check your firewall settings to ensure that connections to TMDb are not being blocked. Ensure your network can reach TMDb’s servers.

6. DNS Resolution within Docker

DNS resolution within Docker containers can sometimes be problematic, especially if the host machine's DNS settings are not correctly propagated to the containers. Here are some ways to address DNS issues:

  • Specify DNS Servers: You can specify DNS servers when running the Docker container using the --dns flag:

    docker run --dns 8.8.8.8 --dns 1.1.1.1 ...

    This command instructs the container to use Google's public DNS (8.8.8.8) and Cloudflare's DNS (1.1.1.1). You can specify multiple DNS servers for redundancy.

  • Docker Compose: If you are using Docker Compose, you can set DNS servers in the docker-compose.yml file:

    version: "3.8"
services:
  moviepilot:
    image: your-moviepilot-image
    dns:
      - 8.8.8.8
      - 1.1.1.1
    ...

  • Docker Daemon Configuration: You can also configure the Docker daemon to use specific DNS servers, which will apply to all containers. Edit the Docker daemon configuration file (usually /etc/docker/daemon.json on Linux) and add the dns key:

    {
  "dns": ["8.8.8.8", "1.1.1.1"]
}

    After modifying the daemon configuration, restart the Docker service for the changes to take effect.

7. Timeout Settings

The timeout errors reported in the logs suggest that the application is unable to establish a connection within the default timeout period. You can try adjusting timeout settings to see if it resolves the issue:

  • Increase Timeout Values: Check if MoviePilot has configuration options to increase timeout values for HTTP requests. These settings might be in the application’s configuration file or settings panel. Increasing the timeout can give the application more time to establish a connection, especially in networks with high latency.

  • Docker Client Timeout: The Docker client itself has timeout settings. If you are running commands that involve network operations, such as pulling images, you might need to adjust the client timeout. This can be done by setting the DOCKER_CLIENT_TIMEOUT environment variable.

8. Check Container Resources

In some cases, resource constraints on the Docker container can lead to network issues. If the container is starved of CPU or memory, it might not be able to handle network connections properly. Monitor the container’s resource usage to ensure it has sufficient resources.

  • CPU and Memory Limits: Check if you have set any CPU or memory limits on the container. If the limits are too low, increase them to see if it resolves the issue.

  • Docker Stats: Use the docker stats command to monitor the container’s resource usage in real-time:

    docker stats <container_id>

9. Plugin-Specific Issues

If the problem is isolated to specific plugins, the issue might be with the plugin itself rather than the overall MoviePilot setup. Here are some steps to troubleshoot plugin-specific issues:

  • Check Plugin Repository: Verify that the plugin repository is accessible and that the plugin package files are available. If a repository has been removed or is temporarily unavailable, it will cause installation errors.

  • Plugin Dependencies: Ensure that all plugin dependencies are installed. Some plugins might require specific libraries or other plugins to be installed first. Check the plugin’s documentation for dependency information.

  • Plugin Compatibility: Confirm that the plugin is compatible with your version of MoviePilot. An outdated or incompatible plugin can cause installation issues.

10. Review Logs and Seek Community Support

If you have tried the above steps and are still facing issues, review the logs for any additional clues. The logs often contain detailed error messages that can help pinpoint the problem. Also, consider seeking support from the MoviePilot community.

  • Examine MoviePilot Logs: Check the MoviePilot application logs for detailed error messages. These logs can provide valuable insights into the cause of the problem.

  • Community Forums and Channels: Post your issue on MoviePilot community forums or support channels. Other users or developers might have encountered similar issues and can offer solutions or suggestions.

By systematically following these troubleshooting steps, you should be able to identify and resolve most MoviePilot plugin installation errors related to request failures and plugin retrieval issues. Proper network configuration, DNS resolution, and resource allocation are key to ensuring a smooth experience with MoviePilot.
