Hey, thanks for the detailed report.
I see you’re hitting the same issue (error 57 + resource_exhausted) that we’ve fixed over the last 2 days in a few cases. The main cause was problematic MCP servers.
Try this:
-
Cursor Settings > Tools & MCP
- Check if you have any MCP servers connected
- If yes (especially Perplexity MCP or custom servers), temporarily disable them
-
Cursor Settings > Models
- Make sure Override OpenAI Base URL is turned off
- If you have third-party API keys (OpenAI/Anthropic), temporarily disable them too (just toggle off)
-
Fully sign out and sign in (Cursor Settings > Sign Out, then Sign In)
-
Create a new test chat in a different project
This helped in identical cases:
- Cursor completely unusable - "Provider Error" on all models
- Connection problems with various models despite clean network diagnostics and having tried to switch to HTTP/1.1
Let me know if this helps. If not, I’ll ask for extra diagnostics, but I suspect it’s MCP.
