Self-signed certificate not verified for completion

[tblattner]

What happened?

Using the "Custom OpenAI" provider.

I have two models setup. One for chat, and the other is a completion model (StarCoder2). Both use self-signed certificates that I have added to the trust list in the JetBrains "Server Certificates". I also tested with enabling the option "Accept non-trusted certificates automatically".

The chat model works fine. The completion model is throwing a ProxyAI error that the certificate is not verified.

Backend uses vllm as the model provider.

Relevant log output or stack trace
