Common Causes of Zoom Error Code 10004

Here are the top causes of Zoom Error Code 10004, along with some lesser-known ones:

  • Internet Connectivity Issues: A spotty or slow internet connection is one of the most common culprits. This prevents Zoom from establishing a stable connection with its servers. Issues like low bandwidth, network congestion, or intermittent drops can trigger this error.
  • Outdated Zoom App: Not keeping the Zoom desktop client or mobile app updated means missing out on important bug fixes and patches. Older versions may not be compatible with the latest server-side changes, resulting in Error 10004. 
  • Zoom Server Errors: Temporary outages or maintenance downtimes on Zoom’s end where the servers are unavailable even with a reliable internet can lead to this error display. 
  • Firewall Blocks: Overly restrictive firewall policies on the device or network that block necessary outbound access to Zoom servers are a frequent cause. Adding Zoom as an exception usually solves it.
  • Corrupted Installation: Over time, install issues ranging from missing dependencies to file corruptions can build up and disrupt the Zoom experience. A reinstallation addresses this.
  • Hardware Incompatibility: In rare cases, outdated devices or unsupported operating systems whose specifications are below Zoom’s requirements can trigger this error. 
  • Cache Buildup: An accumulation of temporary files, logs, cookies, and other cache contents related to previous Zoom sessions clogging up the device leads to Error 10004 until cleared.

Checking Your Internet Connection

Just as you would first do, check your internet connection, and if it is unstable or weak, it could be the main problem. To verify that the network is the reason for the problem, try opening another device, say a smartphone, which is linked to the same network as that of the computer that has the problem. Open some sites and test your connection speed. 

The fact that the computer can be your main workstation is another benefit. Speedtest is a known tool used to check internet performance. You need to visit the control panel and check the speed to see if the results are lower. Here, traffic control is enforced, e.g., logging onto the router admin page to view network activity, and resources such as bandwidth usage can be used to follow this clue. 

Updating Your Zoom Application

Here are the step-by-step instructions with screenshots to update the Zoom application:

  1. Open the Zoom app and login to it with your login details. the main Zoom pane is what you will observe.
  1. Click on the profile icon, which you will find at the top-right part of the interface.
  1. Browse to the dropdown menu “Check for Updates.”
  1. Zoom will look at whether an update has been released.
  1. If there is an update available, you will find it on the top right of the page in the form of a button saying “Update” next to your profile picture. Click on it.
  1. When a user opens the first-time app, i.e. the user who has no knowledge on our products, a popup notification will appear on the top of the screen to show the updated new features and enhancements. Press the button with label “Update” when all updates are done with.

  1. Nowadays, when you start your Zoom app, this app will automatically get updated in the background. You will have to do nothing for that.

Verifying Zoom Server Status

The first step is to always verify the Zoom server status. It gives them a chance to check whether the problem is on Zoom’s end or the device they are using before they can provide support. To check the status of the server, go to from the web browser that you use. The dashboard’s main screen has various indicators that track the real-time status of key services like Zoom Meeting, Zoom Video Webinars, and Zoom Chat. 

This is a sign that the service is functioning at its usual level but may also be a sign that the problem is being contained. While Zoom comes with a seamless and fast experience, it can also miss the mark when it comes to server outage or degradation, and users might have to wait for Zoom to resolve the server-side issue. Rival products like Microsoft Teams and Cisco Webex also provide the same kind of server status monitoring pages that are accessible to the public.

Tweaking Your Firewall Settings

Here are the steps with screenshots to tweak the firewall settings on Windows to allow Zoom:

  • Make sure that Zoom is allowed through your Windows firewall settings. If your Windows Defender Firewall is prohibiting Zoom from passing through, here’s what you should do:
  • Launch the Windows Security app by clicking the Start button and typing “Windows security.” Under Firewall & network protection, select Allow an app through the firewall. Next, click Change Settings. 
  • In the Allowed apps window, scroll down and check if you see Zoom under the list of allowed apps. If it’s there, ensure it has permission to access both private and public networks. 
  • If you don’t see Zoom in the list, click Allow another app. Then browse to the location where Zoom is installed, which is typically Program Files > Zoom > Zoom.exe. Once selected, click Add. 
  • Now, Zoom will be added to the allowed apps list. Make sure to allow access to both private and public networks. Click OK to save the changes.

Additional Tweaks and Optimizations

Here are some additional tweaks and optimizations that can be tried to fix Zoom Error Code 10004:

  • Update Other Apps: Remember to update not only your main applications but also other applications installed on your device. Sometimes, legacy software may not mesh with Zoom, too.
  • Disable Startup Apps: My first step is to enter Task Manager and open the Startup tab. Select the apps that are set to run automatically but which aren’t needed and disable them. This indicates that the software does not rely on those to run. 
  • Clear Browser Cache & Cookies: For the operating system, amazing browsers like Chrome/Firefox, click the Settings tab and go to Privacy to clear the caches, cookies, and other site data.
  • Check for Malware: A full system scan, and check using your anti-virus to see if there is any malware infection like ransomware that has been holding the official Zoom program.
  • Reboot in Safe Mode: Safe Mode needs to be restarted for PC/Mac to load; this will cause the basic essential drivers to load. If Zoom gives it up, it suggests that the app is the conflictant 3rd-party. We suggest you to try downloading and playing the game.
  • Assign More RAM: For PCs, open System Properties window, select the Advanced tab and choose Hard Drive to increase the size of Virtual Memory paging file which works best in terms of memory management and zoom performance.
