Hi there, @Fone520! I'm Dosu, your friendly neighborhood bot here to help you tackle bugs, answer questions, and guide you towards contributing. I'm ready to assist you while we wait for a human maintainer. 🚀

To address the internal server communication errors with the model plugin in your self-hosted Dify version 1.3.1 setup using Docker, consider the following steps:

  1. Replace localhost with host.docker.internal:
    Modify your service configuration to connect to host.docker.internal instead of localhost. This change allows Docker containers to access services running on the host machine.

    http://host.docker.internal:11434

  2. Set Environment Variables:
    Depending on your operating system, set the OLLAMA_HOST environment variable to 0.0.0.0 to allow connections from Docker containers.

    • Mac:
      Use launchctl to set the environment variable:

      launchctl setenv OLLAMA_HOST "0.0.0.0"

      Then, restart the Ollama application.

    • Linux:
      Edit the systemd service for Ollama:

      [Service]
Environment="OLLAMA_HOST=0.0.0.0"

      Reload systemd and restart Ollama:

      systemctl daemon-reload
systemctl restart ollama

    • Windows:
      Edit the system environment variables to include OLLAMA_HOST and restart Ollama from a new terminal window.

These steps should help resolve the internal server communication errors in your Docker setup [1].
