6 Ways to Fix Zoom Error Code 5003
The Zoom desktop client displays the “Error code: 5003” when it can’t connect to Zoom servers. Problems with the network connection or Zoom’s servers often cause this error. Here are several ways to troubleshoot Zoom’s error code 5003 on Windows and Mac computers.

1. Check Zoom Server Status
Zoom may not work on your device if there’s an issue with Zoom’s server. Before trying any troubleshooting fixes, check that Zoom’s servers are operational.
Open your web browser and visit the Zoom Service Status website (status.zoom.us). If Zoom Meetings status doesn’t read “Operational,” the Zoom application may not work correctly on your PC or MacBook.

Keep an eye on the server status page and try using the Zoom app when the server becomes operational again. Contact Zoom Support if the server outage persists for too long.
2. Troubleshoot Your Internet Connection

If your browsers don’t load Zoom’s website and the desktop app isn’t working, that could be because the video conferencing service is blocked in your router or firewall settings. Contact your network administrator to verify that you can use Zoom on the network.
Disable your firewall, antivirus, VPN, or any parent control software that might block access to Zoom. If you use Windows, the Network Diagnostics tool might fix problems with your connection and internet speed.
Using a manual proxy server can also cause network-related errors in Zoom. Disable your computer’s manual proxy setup and try using Zoom again.
In Windows, go to Settings > Network & internet > Proxy > Manual proxy setup, toggle off Use a proxy server, and select Save.

To disable proxies in macOS, head to System Preferences > Network > Wi-Fi > Advanced > Proxies, uncheck all protocols, and select OK.
