In this article, we will be going through the error code 5003 to provide you some methods that can circumvent the issue. As it turns out, the said error code appears when your system is not able to establish a connection with the Zoom servers. This means that something on your system is interfering with the desktop client and thus, preventing it from establishing a connection. As a result, you are not able to join meetings and the mentioned error message pops up. There are different factors that could actually trigger this behavior. Let us go through them one by one. With that said, you probably have established an understanding of what could be causing the error message. Now that we have gone through the potential causes of the issue, let us go through the different methods that you can implement to get the issue resolved.
Method 1: Uninstall Third-Party Antivirus
As you are probably aware at this point, the error message comes up when your desktop client cannot establish a connection with the Zoom servers successfully. This occurs when something on your system is blocking this process or simply interfering with it. Antivirus software is widely known to be interfering with other applications installed on your system to make sure that they are safe to use. While this is appreciable, oftentimes they can trigger a false alarm that stops certain applications from working as intended. In such a scenario, you will have to completely turn off the antivirus software on your system and then try joining a meet on Zoom. In case it works out and you don’t get the error message, then that means the issue is being caused by the third-party antivirus software on your system. If this is applicable to you, what you can do is completely remove the antivirus from your system and look for a better replacement. It is recommended that you uninstall the antivirus software and then reboot your system before checking if the issue has been resolved. In addition, if you have a VPN running in the background, turning that off might also help as certain VPNs have poor connection or the connection could simply be blocked. Once you have turned it off, check if that resolves the issue for you.
Method 2: Reset Network Adapter Settings
In some scenarios, the issue can also be caused by your network setting as we have mentioned above. What you will have to do, in such a case, is to simply reset the network adapter settings on your system and then try to see if the issue has been resolved. The network adapter settings can be easily reset, just follow the instructions given down below:
Method 3: Change DNS
