Describe the Bug

~2hours ago sending anything to the agent chats results in “Planning next steps” for a while, then infinite “Reconnecting…”. Here are the devtools logs:

Does this stop you from using Cursor

Yes - Cursor is unusable

I’ve just found out that happens only in WSL which i’ve been using for a while. Everything works just fine without the WSL connection

Hey, thanks for the report and for digging deeper yourself. It’s great that you identified WSL as the source of the issue.

That’s an important find. We have a few known edge cases with WSL environments, especially around remote extensions and path resolution, but this specific issue with agent stream cancellation is new.

So the team can investigate properly, could you share a bit more:

  • Which WSL version are you using (WSL1 or WSL2)?
  • Which Linux distro are you using in WSL?
  • Do you have any extensions installed in the WSL environment? You can check in the Extensions view.

For now, the workaround is to work locally without the WSL connection, as you already found. I’ll pass this bug to the team along with your details.

Cursor stopped working even without WSL after I tried to send a request to Opus 4.6.
