get error:

HTTPSConnectionPool(host='api.baichuan-ai.com', port=443): Max retries exceeded with url: /v1/chat (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f8c4821beb0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution'))

Troubleshoot:

  1. I checked the server's network configuration, I can telnet 443 port of api.baichuan-ai.com from server correctly;
  2. I've captured the packets on server when I was veirfying keys, but havn't seen any trasaction between server and model providers.

This looks like a DNS resolution failure in the Docker container. Can you please check if you can access it properly within the container?
