Errors 104101 to 104118 indicate your device failed to connect to Zoom’s servers. There are multiple causes for these errors. Perhaps your antivirus or firewall is blocking the connection. Or you’re experiencing network connection issues.

Without further ado, let’s see how you can fix Zoom errors 104101, 104102, 104103, 104104, 104105, 104106, 104110, 104111, 104112, 104113, 104114, 104115, 104116, 104117, and 104118. Remember, although this may seem like a long list of different errors, they all share the same root-cause.

Troubleshooting Zoom Errors 104101 to 104118

Check Your Network Devices and Settings

First of all, ensure your modem/router is working properly. If you haven’t unplugged it in a long time, go ahead and disconnect the power cable. Also, check if there are other devices that might be interfering with your router and remove them from that area. If you’re using an old router model, maybe it’s time for an upgrade.

On the other hand, if you’re experiencing bandwidth issues, switch to a cable connection. If that’s not possible, go to your router settings and enable a different Wi-Fi channel. Make sure you’re not in a Wi-Fi dead zone. Don’t forget to disconnect all the other devices that are using the connection.

Disable Your Firewall and Antivirus

Your firewall or antivirus might be preventing your computer from connecting to Zoom’s servers. The quickest way to test that is by simply turning off your firewall and antivirus protection. Check if your Zoom error persists.

If it’s gone, this is a pretty clear indication your antivirus/firewall was the culprit. Try whitelisting Zoom in your antivirus and firewall settings.

If you’re using Windows Defender:

  1. Navigate to SettingsUpdate & SecurityWindows SecurityVirus & threat security virus and threat protection manage settings
