Cursor IDE
Describe the Bug
When I attempt to work with GPT models now, they never actually get past the first few tokens of thinking before reporting that the model is unreachable. I have attempted to disable HTTP2 (per a conversation I read here about a similar issue). This is not intermittent per se - I just can’t use them and haven’t been able to use them since this past weekend. Prior to that, everything worked fine. I am able to use all other models without any issue. The only intermittent piece is that sometimes I get a few tokens (just got plan mode to ask two questions, then nothing happened after I responded), other times it just spins on “planning next moves” then drops out. I have tried codex and regular GPT in various thinking levels with the same results for all. This happens in new sessions, current sessions, with or without attachments, etc…
I haven’t made any changes to my network config at home or on my PC since they last worked.
