Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
I cannot create new chats in Cursor. Each attempt fails with the following error:
Request ID: 0f9061c2-c37a-41fe-8b20-c42b6d1f3d7f
ConnectError: [internal] 1185413480192:error:10000410:SSL routines:OPENSSL_internal:SSLV3_ALERT_HANDSHAKE_FAILURE:../../third_party/boringssl/src/ssl/tls_record.cc:486:SSL alert number 40
I also noticed that the domain api.cursor.sh does not resolve for me.
dig, nslookup, ping, and curl all fail to resolve this host across multiple DNS providers (1.1.1.1, 8.8.8.8, 9.9.9.9).
Other Cursor domains (like api2.cursor.sh) resolve and respond normally.
Things I already tried:
• disabling VPN
• restarting my Mac
• clearing the Cursor cache
• fully reinstalling Cursor
• trying different networks
• logging out/in
• flushing DNS cache (dscacheutil, mDNSResponder)
• changing system DNS servers
• verifying that no entry exists in /etc/hosts
• testing with curl, dig, nslookup, ping — all show NOANSWER for api.cursor.sh
Steps to Reproduce
1. Open Cursor
2. Try to create a new chat
3. The error appears immediately
4. Network-level checks (ping, dig, nslookup) show that api.cursor.sh does not resolve from any DNS server
Expected Behavior
Cursor should resolve and connect to all required API endpoints, including api.cursor.sh, and allow creating new chats without SSL or DNS errors.
