Source-checked About 5 minutes5 official sources

Quick fix

Open zoom.us and Zoom Status. If both load, open Zoom Workplace, press Ctrl+Alt+Shift+D, and run Smart TestNetwork TestStart Test. Match the result below; do not disable the firewall or reset Windows blindly.

Check Zoom and the web

In a browser, open zoom.us and zoomstatus.com. If Zoom Status reports an incident, wait and monitor it; if ordinary trusted sites also fail, fix the general internet connection first. If a meeting is starting now, use the invitation's Join from Browser option when the host allows it, or join temporarily from the Zoom mobile app.

Run Zoom's Network Test

Open Zoom Workplace on Windows and press Ctrl+Alt+Shift+D. Select Smart TestNetwork TestStart Test, wait for Network Information, MTR, and Service Status, then select View Results. Keep the exact failure and time; the test is more useful than guessing at DNS, drivers, or Windows resets.

Compare one trusted network

Run the same test once on another trusted network, such as a personal phone hotspot. If Zoom works there, return to the original router, VPN, proxy, firewall, or administrator; if it fails on both networks while Zoom Status is healthy, continue with the app check. Do not use a public network for a private meeting merely to complete this test.

Update Zoom Workplace

Sign in to Zoom, select your profile picture, and choose Check for Updates. Install the offered update, reopen Zoom, and rerun Network Test. If Check for Updates is missing on a managed installation, ask the administrator to update Zoom rather than downloading around its policy.

Send the result to the right owner

On a personal network, fully quit Zoom, restart the router once, and rerun the test. On a work or school network, give IT the exact error, time, Network Test result or exported log, and Zoom's current firewall and proxy page; do not disable security or add broad rules yourself.

Verify with a test meeting

Return to the intended network and open zoom.us/test. Success means the Zoom test meeting opens and the Network Test no longer reports the same service or connection failure; stop there instead of continuing through unrelated repairs.

If it still does not work

  • If the browser works but the Zoom app fails on every trusted network, reinstall the current Zoom Workplace app only after updating and preserving the Network Test result.
  • If only one meeting link fails, open Zoom, choose Join, and enter the meeting ID and passcode manually; the meeting may be invalid, expired, or restricted rather than a network failure.
  • If a VPN or proxy is required by work or school, do not turn it off permanently. Give the administrator the Network Test result and Zoom's current outbound domain and port requirements.
  • If Zoom Status is healthy but the test reports a service failure, record the result and time and retry once before contacting Zoom Support.

Sources and verification

Checked against official documentation on . Scope: Windows. Current first-party documentation was source-checked; the Network Test still requires a hands-on Windows retest before advancing any last-tested claim.
