1. Restart the zoom

2. Check the Zoom servers

Before moving on to a complex solution, you should try this step. If Zoom’s servers are currently down, there is nothing you can do on your end to fix error code 5003 because the problem is on their end.

To check this, visit the official Zoom website, where the status of their servers is displayed. On the site, make sure that all of its servers are operational. You can also visit Downdetecter and check if other users are reporting the same issue or not.

3. Check the internet connection

The next thing to do is to check the speed of your internet connection. Because the error code 5003 is related to connectivity issues, your connection may not be stable or too slow to make a video call.

You can visit Fast.com or use apps like Speedtest to confirm the current internet speed on the device.

4. Disable antivirus and VPN

This step mainly applies to PCs because Windows users are the ones who use third-party antivirus on their devices. Normally, these applications will not affect other installed programs.

Some free VPN or antivirus services can interfere with games and apps like Zoom. This may be because services can sometimes restrict or even stop the internet connection to applications that try to connect online.

Disable VPN for zoom

Another reason could be the automatic region selection by VPN. If Zoom is prohibited in your country and the installed VPN uses this location, you will not be able to access the Zoom app.

We suggest you open your VPN and Antivirus app, temporarily disable it, and then try joining the Zoom room.

5. Disable the firewall

You need to make sure that the Zoom app can bypass the firewall on your PC or Mac to use internet connectivity on the device.

In Windows, go to Windows Defender Firewall> Allow an app through Windows Defender Firewall> find the Zoom app and make sure it’s allowed on your firewall.

6. Disable proxy servers

Like Windows Firewall, a proxy server acts as a layer of security between your system and the Internet. Your proxy server settings can cause problems with the Zoom app and it tries to prevent it from accessing your network.

In such cases, you should disable proxy servers in the Windows Settings menu. Follow the steps below.

Step 1: Use Windows + I keys and open the Windows Settings menu.

2nd step: Go to Network and Internet> Network settings> Proxy.

Step 3: Make sure “Use a proxy server” is disabled.

Step 1: Press the Windows key and open Device Manager.

2nd step: In Device Manager, click Network Adapters to expand it.

Uninstall the drivers

Step 3: Finally, right click on your current network card and select Uninstall device.

8. Update the Zoom application
