How to Fix Zoom Error Code 5003
Zoom generally works well and makes video conferencing efficient and straightforward. However, issues do occur sometimes.
If you see an error code 5003, that means that there’s a problem with establishing a connection with the Zoom’s servers. There could be several reasons why that’s happening.
It could be a firewall issue, an antivirus software block, or you might have a corrupt wireless driver. In this article, we’ll explain how to fix these issues.
Network Firewall or Proxy
If you’re trying to connect to Zoom, but you’re on a network that has a firewall or proxy, you might see the error code 5003 on your screen. That could happen if you’re using your computer or mobile device at a university or in some other organization that has network access restrictions.
In that case, you should contact the network administrator so they can check the firewall and proxy settings.
If you need to configure the network firewall, Zoom has a table of protocols and destinations that you can view on their webpage. Also, Zoom recommends that you whitelist the zoom.us page from all the proxy or SSL inspections.
If you’re using AVG antivirus on your device, you might see the error code 5003 when trying to connect to Zoom. In that case, your best course of action is to disable AVG temporarily. Once the Zoom meeting is over, you can reverse the AVG settings. Here’s what you need to do:
- 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.”
You will see the toggle button turn red, and it will say, “Off.” That means that every AVG antivirus feature is disabled. So, make sure that you don’t leave your computer exposed and vulnerable for too long. Also, when you reboot your computer, the antivirus protection will automatically turn on.
Corrupted Wireless Driver
There is a third potential reason why you’re getting the error code 5003 on your screen. Some Zoom users have reported that it was a corrupted wireless driver that was preventing them from connecting to Zoom. If that’s the case, the problem won’t go away on its own. What you need to do is reinstall the wireless driver on your computer.
We’re going to show you how to do that on Windows operating system. The first thing you should do is to uninstall the driver for your Wi-Fi adapter. Here’s what you should do:
- 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’ll see that your network adapter is no longer on the list. Here’s 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’ve successfully reinstalled it.
Other Zoom Connectivity Error Codes
Just like any web-based application, Zoom has many error codes. You might also see the error code 5000 or 5004. Both could imply the same issues related to the error code 5003.
You can check the Zoom Help Center page that lists all the 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 isn’t valid anymore. 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’ll 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.
Resolving Zoom Connectivity Issues
It can be rather annoying when you see the error code 5003 on your screen when trying to hop on a Zoom meeting. But there are ways to fix it. First, check the network you’re using. Is there a firewall?
Are you using AVG antivirus on your device? Finally, try reinstalling the wireless drivers, it can’t hurt. Hopefully, any of these solutions will help you get back to Zoom.
