Does this stop you from using Cursor

Yes - Cursor is unusable

Ok, here’s a request id b514df7f-4e6c-41b7-acb8-f4fff18acd69 it’s now getting stuck in planning next moves and very very slow

also i see a lot of this errors:

[Extension Host] [otel.error] {“stack”:“OTLPExporterError: Bad Request\n\tat IncomingMessage. (/Applications/Cursor.app/Contents/Resources/app/node_modules/@opentelemetry/otlp-exporter-base/build/src/transport/http-transport-utils.js:52:31)\n\tat IncomingMessage.emit (node:events:531:35)\n\tat endReadableNT (node:internal/streams/readable:1698:12)\n\tat process.processTicksAndRejections (node:internal/process/task_queues:90:21)”,“message”:“Bad Request”,“code”:“400”,“name”:“OTLPExporterError”,“data”:“{“error”:“Trace spans collection is not enabled for this user”}”}

in the console log

Another request id 66634404-bd16-453e-83a8-1ccbe81ff13f

Now it’s failing when running git commands

Now things are timing out 7e03c95b-a8be-453f-b1f3-d14c412367b0

Hey, thanks for the report. From the screenshot, I see ConnectError [invalid_argument], network errors, and OTLP 400.

Let’s check the network:

1. Cursor Settings > Network > Run Diagnostics - share a screenshot of the results
2. Cursor Settings > search “HTTP/2” > enable “Disable HTTP/2”, full Cursor restart
3. VPN/proxy/Zscaler - disable temporarily and try again

Also try:

• Settings > Agents > Inline Editing & Terminal > enable “Legacy Terminal Tool”, then Cmd+Shift+P > “Terminal: Kill All Terminals”, restart
• Check git in a regular terminal (outside Cursor) - do the same commands work?
• If MCP servers are configured in ~/.cursor/mcp.json - disable them all temporarily

Could you please share:

• Screenshot of Network Diagnostics
• View > Output > select “Git” - last lines with errors
• New Request ID after trying with HTTP/2 disabled

Similar issue: SLOW or NO response from the agent - resolved via extensions

If timeouts/freezes persist after these steps, I’ll pass it to the engineers.

>Check git in a regular terminal (outside Cursor) - do the same commands work?
Yes

It seems to come and go, I still need to check internall if the VPN configuration (I’m on a work device and we use cloudflare warp) changed.

Also i’m not sure if it’s related but the usage, does not show up anymore (will attach screenshot in a follow up)

And here are the connection logs:
With VPN disabled

and VPN enabled

Usage screenshot

[deanrie]

Thanks for the info. From the screenshots and logs, I see:

• OTLP 400 and ConnectError in the console
• Git commands fail in Cursor, but work in a regular terminal
• Different connection behavior with Cloudflare WARP on/off
• Usage panel is empty

Could you please share:

1. Confirm: Settings > search “HTTP/2” > enable “Disable HTTP/2”, fully restart Cursor and check with Cloudflare WARP turned off
2. Settings > Network > Run Diagnostics - fresh screenshot after step 1.
3. Settings > Agents > Inline Editing & Terminal > enable “Legacy Terminal Tool”, then Cmd+Shift+P → Terminal: Kill All Terminals, restart, check git.
4. MCP: if you have it, disable and check.
5. Run cursor --disable-extensions and test chat/agent.
6. Provide 2-3 new Request IDs after disabling HTTP/2 and WARP.

Let me know if this helped. If not, the issue likely needs deeper investigation, as it’s probably related to your network.

[joaquinP (My Name is)]

Ok, i have some news

Managed to consistently reproduce the problem in a scenario where i have three repositories in the workspace

Request IDs:
db287d51-98a9-4b75-9550-5405596b786e

But this does not happen on every repository i have a single repository that’s not too big

Examples on several different repos:

• e4ec06c9-d634-4de8-90cb-f15209e8df6f

• a2e98b6d-3680-4a8f-85df-96332bda7d05

Here is an example of something more strange:

i’ve configured cursor to “ask every time” and it’s not getting to the point where it’s asking me to run the command (request id: f2705f12-bc9c-43c7-baef-b4d8d96488dd )

More examples:

BAD: 71215170-4a3a-4ed3-95f3-aab756848b0f

Same repo:
WORKS: 15d51a65-6da6-4fb4-b3ae-9d91dfad2524
No works: 651f8f43-3a61-4b32-bb69-32656bfd7266

THe one that works was a chat that was working, the no works is a new chat

Another example with another repo:
No works: 9ca8cb06-6028-4eac-8b85-520a79a21370
Works: 71fc92d9-37f0-4f67-b16b-9a72e7d2babe

This second chat existed already and you can see in the screenshot what it looks like:

It never gets to the point to “ask” me to run it

Here are the console logs, and this happens with/without warp enabled

[joaquinP (My Name is)]

also, no MCP, extensions do not see to affect this at all

[deanrie]

Thanks for the screenshots - I can see that the “Run command” card is freezing and not launching the command.

Please check the following checklist:

1. Settings > Agents > Inline Editing & Terminal → enable “Legacy Terminal Tool”; then Cmd+Shift+P → “Terminal: Kill All Terminals”, restart Cursor.

2. Clean profile: cursor --user-data-dir="CursorTmp/clean1» → first open chat (without repo), then one repository (single-folder). Check running pwd/git.

3. Send: 2-3 fresh Request IDs, screenshot of Help > Toggle Developer Tools > Console, and View > Output > Git (last lines).

Let me know the results - if it still freezes in the clean profile, I’ll pass it to the engineers.

[joaquinP (My Name is)]

Ok,
So i’ve now managed to reproduced with/without warp on a clean profile without even opening a project.

The first chat window that i open works, anything that comes after that is broken and if i close the first chat window everything is broken from then on.
