Source-checked About 10 minutes
Answer
Check Zoom service status and the network, update Zoom, test without VPN or proxy, and allow Zoom through the firewall using the documented ports and domains.
Check service and scope
Verify Zoom status and test whether sign-in, meetings, chat, or all internet access fails.
Restart the connection path
Fully quit Zoom, restart the PC and router, and test a different trusted network without a VPN or proxy.
Update and allow Zoom
Install current Zoom Workplace and allow its signed executables through the firewall; do not disable security globally.
Escalate with evidence
For managed networks, give IT the exact error, time, meeting ID, logs, and Zoom's current ports and domains.
Verify the result
Join a test meeting and verify sign-in, audio, video, chat, and screen sharing on the intended network after each supported change.
