Hey, thanks for your patience. We can see the issue is still happening even after all the troubleshooting steps.
Confirmed, this is a known infrastructure issue and the team is working on it. Your Request IDs have been shared with the engineers as a priority.
While we work on a fix, here are a couple of temporary options:
Use your own OpenAI API key directly (as you noticed, this helps)
Try Claude Sonnet 4.5 instead of Opus. Based on user feedback it’s more stable
About your request for custom base URLs for other providers, I’ll pass that feedback to the team. I get that expectations are higher on the Ultra plan.
I’m escalating this internally and I’ll follow up with an update as soon as we have a clearer fix timeline.
Thanks @deanrie I appreciate the response, but this is the same one I have been getting for weeks. Claude Sonnet 4.5 gives the same issues, but more importantly does not address the issues that the models you advertise and have available, such as GPT 5.2 and Opus 4.5 do NOT work properly.
I think we are beyond the “I’ve escalated this issue” as I have also sent emails to support with no response.
Please review my email to support and let’s try and resolve this matter as I pay a pretty substantial amount to Cursor monthly beyond the $200 fee
@deanrie still doesn’t work even when using my own OPENAI Key
Connection failed. If the problem persists, please check your internet connection or VPN

Again, problem is costing me token usage when the connection breaks, then I have to either open a new agent window or try again, which then requires the agent to send more data to the LLM and thus costing MORE token usage.
Just doing a quick analysis, I am confident in saying that I am paying 1.27x times what I should be because of this

We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.

It’s also generally helpful to create new topics and fill out the bug report template. “Fix this” doesn’t get us very far! Details like what version you’re using are really important here.
