Hey, Same issue for me continuing today Apr 8th. I’m on Mac using Cursor Version: 3.0.13 (Universal), no updates available. Http compatibility mode set to http/1.1 Network diagnostics results: Cursor Network Diagnostic Results DNS: Success Logs : [2026-04-08T17:57:09.487Z] Host: api2.cursor.…

Hey, looks like a few different issues got mixed together here. I’ll reply to each one. @GB_e_Giada_Aicardi : Is the original issue still happening? The details in Post #4 will help a lot. Without them it’s hard to tell what’s causing it. @Mr.Minnu : 30 GB memory use and freezing when opening the ag…
