Go here Download · Cursor

Download for example 1.5 and try that, does it happen with an earlier version?

Thanks. Everything worked fine on the old version. I hope the Cursor team fixes this bug as soon as possible.

Hey, thanks for the report.

This is a known HTTP/2 networking issue. Please try:

I don’t recommend rolling back to an older version. Let me know if it helped.
