Top 8 Way To Fix 5003 Error In Zoom

Top 8 Way To Fix 5003 Error In Zoom

The future of work is moving, and many firms around the world are already implementing new workflows for employees to complete their tasks.

Zoom is the best work from home tool, with an easy-to-use UI and a lot of functions. However, the entire process isn’t as smooth as you might think.

Users have reported experiencing random error 5003 while in the middle of a Zoom meeting.

Zoom, like any other application, has downtimes and issues from time to time. Several customers have reported receiving the error code 5003 whenever they attempt to join a Zoom conference.

If you’re one of them, then let’s go to work on resolving the problem.

1. Restart The Zoom Application

This is the simplest method for resolving the error 5003 in Zoom. The programme occasionally encounters a temporary issue, making it difficult for it to connect to its servers. In this situation, restarting the app would allow it to reload all of its resources, and the temporary problem would be gone.


Users of Windows can look for the Task Manager by pressing the Windows key on their keyboard. Locate the Zoom app in the Task Manager app and end the application’s process.


On Mac, you can use the Command + Space keys to open the Spotlight Search. Try searching for the Activity Monitor and open the app. Locate the Zoom app and hit the Stop button on the menu bar.

Zoom mobile users can use the multitasking menu to force close the app and resume it from the beginning using the app drawer.

2. Verify Zoom Servers

You should try this step before moving on to a more complicated solution. If Zoom’s servers are temporarily down, you won’t be able to fix the error number 5003 on your end because the problem is on their end.

Visit Zoom’s official site, where the status of their servers is stated, to check this. Ensure that all of the site’s servers are up and running. Alternatively, you can utilize Downdetecter to see whether other users are experiencing the same issue.

3. Verify Your Internet Connection

The next thing you should do is verify the speed of your internet connection. Because error 5003 is associated with connectivity issues, your connection may be unstable or too slow to make a video call.

To check the current internet speed on the device, go to or use an app like Speediest.

4. Deactivate VPN And Anti-Virus

Because Windows users are the ones that use third-party antivirus on their devices, this step primarily applies to PCs. Other installed programmes are usually unaffected by these apps.

Certain free VPN and antivirus services, such as Zoom, may cause problems with games and apps. This could be because the services can occasionally limit or even disable internet access for programmes seeking to connect to the internet.

Another cause could be that the VPN automatically selects a region. You won’t be able to use the Zoom app if Zoom is blocked in your country and the installed VPN utilises that location.

We recommend opening your VPN and anti-virus software, temporarily disabling it, and then re-entering the Zoom room.

5. Turn Off Firewall

To use the internet connectivity on the device, make sure the Zoom software can overcome the Firewall on your PC or Mac.

Navigate to Windows Defender Firewall > Allow an App Through Windows Defender Firewall > find Zoom app and ensure it is allowed on your Firewall on Windows.

6. Turn Off Proxy Service

A proxy server, like Windows Firewall, operates as a security layer between your machine and the internet. Your proxy server settings may be causing problems with the Zoom app, preventing it from connecting to your network.

Proxy servers should be disabled from the Windows Settings menu in such instances. Take the actions outlined below.

Step 1: Open the Windows Settings menu by pressing Windows + I.

Step 2: Select Network & Internet > Network Settings > Proxy from the drop-down menu.

Step 3: Make sure ‘Use a Proxy Server’ is disabled.

To see if the error code 5003 still occurs, reopen the Zoom app and try to join a Zoom conference.

7. Network Drivers Must Be Re-Installed

Buggy network drivers installed on the device can cause network connection troubles in Zoom. To uninstall them, follow the procedures below.

Step 1: Open Device Manager by using the Windows key.

Step 2: To expand Network Adapters in Device Manager, click on it.

Step 3:Finally, right-click on your present network adapter and choose Uninstall Device from the context menu.

Restart your computer after deleting your network drivers, and Windows will automatically install the best driver for your network device.

8. Update Your Zoom Application

Maintaining the most recent version of the Zoom app appears to be useful in resolving technical concerns. These updates include helpful bug fixes that may prevent connectivity troubles caused by interfering bugs.

Furthermore, they boost the app’s overall performance. Check for the most recent update available to install under the Zoom settings on Windows or Mac.
