Basic Fixes:
- Disable VPN and firewall: Zoom is banned in several countries, including Iran, Syria, and North Korea, for regulatory reasons. If you are using a VPN on your Windows PC, disable it temporarily and ensure that the Zoom app can bypass the firewall on your computer to use the internet connectivity.
- Check Zoom servers: Using a service like Downdetectors, you may ensure the Zoom servers are not down.
- Restart the app: Restarting Zoom is effective because it can fix minor bugs that trigger that problem.
- Check Internet connection: It’s always advisable to check your internet connection before an important Zoom meeting, especially when using a high-resolution webcam with Zoom backgrounds during long video calls.
- Ensure the date and time are correct on your device: Zoom works with your computer’s date and time, so you should ensure they are correct. If not, they will trigger the problem.
- Reinstall Zoom: You may consider uninstalling your current Zoom installation and downloading and installing a fresh copy. This will be an effective fix if Zoom is corrupted.
Fix 1: Run the Network and Internet Troubleshooter
Windows comes with a built-in Network and internet troubleshooter. It can detect internet errors that may cause the Zoom problem. You may run this tool following the steps below.
Step 1: Press Windows + R to open the Run dialog.
Step 2: Type cmd and hit Ctrl + Shift + Enter to open an elevated Command Prompt.
Step 3: Type the command below and hit Enter.
msdt.exe /id NetworkDiagnosticsWeb
Step 4: Click the Next button and follow the wizard to complete the process.

Fix 2: Clear Temporary Cache
Over time, Windows collects a temporary cache in the background to speed up the frequent tasks on the computer. These cache files can corrupt and interfere with other apps like Zoom. You must remove temporary internet and unnecessary cache files from the system. To do that, follow the steps below.
Step 1: Press the Windows key, search Disk Cleanup, and open the app.
Step 2: Select C: drive from the list and hit Enter.

Step 3: Check the boxes for Temporary Internet files and cache files from the list, click on Clean up system files at the bottom, and hit OK.

Reboot the computer and try using Zoom again.
