I found a similar solved discussion regarding a "[Errno -2] Name or service not known" error in Dify. The solution was to leave the SSRF proxy configuration blank in your environment settings:

api:
  environment:
    # SSRF Proxy server
    SSRF_PROXY_HTTP_URL: ''
    SSRF_PROXY_HTTPS_URL: ''

This approach has been confirmed to resolve similar issues [1]. You might want to try this configuration to see if it resolves the proxy error with the DeepSeek model.

To continue talking to Dosu, mention @dosu.

Hi, @badspider7. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported that running the DeepSeek model in Dify v1.1.2 (self-hosted via Docker) fails with a proxy and DNS resolution error for api.deepseek.com.
  • Other models work fine in your setup, and the issue persists even after disabling VPN.
  • You mentioned intermittent past success with the model.
  • A contributor suggested clearing SSRF proxy environment variables as a fix, but you confirmed this did not resolve the problem.
  • The issue remains unresolved and may require further investigation or alternative solutions.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of the dify-official-plugins repository by commenting here.
  • If I do not hear back within 5 days, I will automatically close this issue.

Thank you for your understanding and contribution!
