Hey @huwei! 👋 I'm here to help you with any bugs, questions, or contributions you have for the project. I'll do my best to assist you while you wait for a human maintainer.

I found a similar closed issue related to SSL errors in a self-hosted Dify setup without a proxy. The suggested solution involves checking and modifying the following settings in your Docker environment:

  1. Enable HTTPS: Ensure that NGINX_HTTPS_ENABLED is set to true in your Docker environment configuration to enable HTTPS and allow SSL connections.

  2. SSL Certificates: Verify that the SSL certificate and key files (dify.crt and dify.key) are correctly configured and accessible by the Docker container. These files should be placed in the appropriate directory and referenced correctly in your configuration.

  3. SSL Protocols: Ensure that the SSL protocols are correctly set. The default protocols are TLSv1.1, TLSv1.2, and TLSv1.3. You might want to adjust these if your environment requires different protocols.

  4. Network Configuration: Double-check your network settings to ensure there are no firewall rules or network policies blocking SSL traffic.

These steps should help resolve the SSL errors you're experiencing [1].
