How to Fix Zoom Error Code 10004 in 2025

1. Reinstall the Zoom Application

For Windows Users:

A common cause of Error 10004 is a corrupted or incomplete installation. Here’s how to uninstall and reinstall Zoom properly:

Click on the Start Menu and type Zoom in the search bar.
Right-click the Zoom app and select Uninstall.
After the uninstallation is complete, open your browser and visit the official Zoom website.
Download the latest version of the Zoom client.
Open the .exe file, accept the terms and follow the installation prompts.
Once installed, log in to your Zoom account and check if the error has been resolved.

For Mac Users:

If Zoom is currently open, press Command + Q to quit the app.
Open Finder and navigate to the Applications folder.
Drag the Zoom app to the Trash or right-click and select Move to Trash.
Empty the Trash to remove the application completely.
Launch Safari, visit Zoom.us, and download the Zoom client for Mac.
Install the app and log back into your account.

2. Check Zoom Server Status

Sometimes, the error is not from your end at all. A server-side issue may be causing the connection failure.

Open your browser and visit status.zoom.us.
Scroll down to find your country or region.
Check if all services (Meetings, Chat, Webinar, etc.) show Operational status.
If any service is Degraded or Under Maintenance, wait until Zoom resolves the issue.

Technewztop recommends checking the server status before attempting other fixes, especially if the error appeared suddenly during a previously stable session.

3. Update the Zoom App

An outdated Zoom app is another major reason for the error. Keeping the app updated ensures compatibility with Zoom servers and security protocols.

To Update Zoom:

Launch the Zoom desktop client.
Click your profile icon in the upper-right corner.
Select Check for Updates from the dropdown menu.
If an update is available, a prompt will appear. Click Update and let the process complete.
Restart the app once the update is installed.

Performing regular updates avoids technical glitches and improves app performance. Technewztop suggests enabling auto-update if possible.

4. Allow Zoom Through Firewall Settings

Sometimes, your system’s firewall or antivirus software might be blocking Zoom from accessing the internet properly.

For Windows Users:

Open the Start Menu and search for Allow an app through Windows Firewall.
Click Change Settings.
Scroll through the list and find Zoom Video Communications.
Make sure both Private and Public checkboxes are ticked.
Click OK to apply changes.

For Mac Users:

Go to System Settings > Network > Firewall.
(Or: System Preferences > Security & Privacy > Firewall for older Macs.)
Click the lock icon in the lower-left and enter your admin password.
Click Firewall Options.
Press the + icon and add Zoom from your Applications list.
Select Allow Incoming Connections.
Click OK and close the settings.

By allowing Zoom full access, you eliminate potential connection blocks caused by security tools.

5. Clear Zoom Cache and App Data

Corrupted cache files may prevent Zoom from functioning correctly. Clearing them often resolves stubborn issues.

Steps to Clear Zoom Cache on Windows:

Press Windows + R to open the Run dialog box.
Type %appdata% and press Enter.
In the file explorer window, find and open the Zoom folder.
Delete all contents inside this folder.
Restart Zoom and check if the issue persists.

6. Check Your Internet Connection

A poor or unstable internet connection can interrupt the communication between your Zoom client and the server, leading to Error Code 10004.

To Test Your Internet Speed:

Open a browser and search for Internet Speed Test or go to speedtest.net.
Run the test and ensure you have at least 5 Mbps upload/download speed for optimal Zoom performance.
If the results are poor, try:
1. Restarting your router
2. Switching to a wired connection
3. Contacting your ISP for assistance

7. Update Your Operating System

Compatibility issues between your device OS and the Zoom client may also cause errors.

For Windows:

Go to Settings > Windows Update.
Click Check for Updates and install any pending system updates.
Restart your system once the updates are complete.

For Mac:

Go to System Settings > General > Software Update.
If an update is available, download and install it.
Reboot your device.

Keeping your OS updated ensures that all apps, including Zoom, function efficiently and securely.

8. Use VPN or Disable It

In rare instances, using a VPN may help bypass region-specific server issues. Conversely, if you’re already using a VPN, it might be interfering with the Zoom connection.

Tips:

Try toggling your VPN on or off.
Test Zoom with and without the VPN to see which provides better results.
If using a VPN, select a server location close to your actual region for better performance.

9. Create a New User Profile (Advanced Fix)

Sometimes, a corrupt user profile may cause app-related issues. Creating a fresh profile can help you start with default settings.

For Windows:

Go to Settings > Accounts > Family & other users.
Click Add someone else to this PC and follow the prompts.
Log in to the new profile and install Zoom.

For Mac:

Go to System Settings > Users & Groups.
Click the lock icon, authenticate, and then click the + icon.
Create a new user account, log into it, and try running Zoom.

10. Contact Zoom Customer Support

If none of the above methods work, it’s time to seek professional assistance. You can raise a support request on Zoom’s official help portal.

Visit support.zoom.us.
Sign in with your Zoom credentials.
Select the issue category and describe your problem in detail.
Submit the ticket and wait for a response from the Zoom support team.
