Do you need to file an issue?

• I have searched the existing issues and this bug is not already filed.
• I believe this is a legitimate bug, not just a question or feature request.

Describe the bug

This is like #464. I have already upgraded to v1.4.1.

Llm test failed. Embedding model test worked.

Steps to reproduce

run llm test

open settings > llm > test llm
llm test would fail with ssl self-signed certificate error

Expected Behavior

http ssl connection to llm connection should work like curl -k
