Zoom Error Code 5003: See How You Can Fix It Easily

Zoom Error Code 5003 Solutions

In relation with some issues, below are some solutions or how to fix Zoom Error Code 5003.

Network Firewall or Proxy

If you are trying to connect to Zoom, and at the same time your device is on a network that has a firewall or proxy, you might come across the Zoom Error Code 5003 on your screen. This could happen if you are using a computer or mobile device at a university or other organizations that have access restrictions on their network.

To fix this issue, you need to contact the network administrator so they can check the firewall and proxy settings.

If you have to configure the network firewall, Zoom has a table of protocols and destinations that you can view on their webpage. They also recommend that you whitelist the zoom.us page from all proxy or SSL inspections.

AVG Issue

If you have the AVG antivirus installed on your device, you might see the Zoom Error Code 5003 when you are trying to connect to Zoom. In such a situation, the best fix is to disable AVG temporarily. Once the Zoom meeting is over, you can then reverse the AVG settings. Below are some steps you can take.

  • Right-click on AVG on your computer screen.
  • When a menu pops-up, select the green toggle button that says, “Protection is ON.”
  • When prompted to confirm the selection, click “Yes.”

When you might have done this, you will see the toggle button turn red, and it will say, “Off”. This means that every AVG antivirus feature has been disabled. Just ensure that you do not leave your computer exposed and vulnerable for a long time. Also, when you reboot your computer, the antivirus protection will automatically turn on.

Corrupted Wireless Driver

This is another potential reason why you might see the Zoom Error Code 5003 on your screen. Some users have reported that it was a corrupt wireless driver that was preventing them from connecting to Zoom. In this case, all you need to do is to re-install the wireless driver on your computer.

Let me show you how you can do that on your Windows PC. The first thing you need to do is to uninstall the driver for your WI-Fi adapter. Below are the steps to do that.

  • Press the Windows key + X and then select “Device Manager.”
  • Next, find your wireless network adapter and right-click on it.
  • Select “Uninstall device.”
  • Make sure to check the box that says, “Delete the driver software for this device.”
  • Select “Uninstall” again.

After that, you will see that your network adapter is no longer on the list. Here is how to install it again.

  • Go back to the “Device Manager.”
  • Then select “Network Adapters” followed by “Action.”
  • Select “Scan for hardware changes.”
  • Click on “Network Adapters” again.

At this point, your Wi-Fi adapter should appear on the list again. And that means that you have successfully reinstalled it.

Some Other Zoom Connectivity Error Codes

Zoom has many error codes, just like any other web-based application. You might come across others like Zoom Error Code 5000 or 5004. Both could imply the same issue related to the Zoom Error Code 5003.

You can check the Zoom Help Center page to see the list of all potential error codes linked to problems with connecting to the Zoom servers. Other errors, however, have nothing to do with connectivity.

For example, error code 2008 means that a webinar license has expired or is no longer valid. Or, if you see the 10002 error code during Zoom installation, it means that your antivirus software has captured Zoom files needed for the installation. That means that you will probably have to go through the installation process manually.

The 10006 error code might mean the same thing, or it could signify that the target disk where you’re downloading Zoom is full.

Conclusion

It is quite annoying to see the Zoom Error Code 5003 on your screen while trying to join a Zoom meeting, but there are ways you can fix it. Just as I have explained in this post, check if you are having the issues and carry out the appropriate fix. Hopefully, the solutions I have outlined right here can help you get connected back to Zoom.
