Solutions to Fix Zoom Errors 5000, 5003 and 5004

⇒ Quick Tip: Don’t forget to check the Zoom Service status. Maybe the error you’re experiencing is caused by a known issue. In this case, there’s no need to pursue any troubleshooting steps. Wait until Zoom has fixed the problem on their end.

Check Your Firewall and Proxy Settings

If you’re connected to a network that uses a firewall or a proxy, the best approach is to contact the admin and ask them to check the network settings. They can find all the information they need on Zoom’s Support Page.

Close Background Programs

The programs and processes running in the background may prevent your computer from connecting to Zoom’s servers. Close all the other active programs, including your VPN.

Another method to close background programs is to clean boot your computer.
