Zoom errors 5000, 5003, and 5004 indicate your computer failed to connect to Zoom’s servers. Maybe one of the programs installed on your device is blocking your connection to Zoom. Or your network settings don’t let you connect to Zoom’s servers.
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.
One way to do that is by launching the Task Manager. Click on the Processes tab, and right-click on the program you want to close. Then select End Task.
Another method to close background programs is to clean boot your computer.
Disable Your Antivirus and Firewall
Temporarily disable your antivirus and firewall. If there’s no error, whitelist Zoom. This is a clear indication that your antivirus or firewall is blocking the service.
