3] Delete the JSON files

JSON files are Microsoft files that have all the information regarding configuration, authorization, settings, and so on. Therefore, if they get corrupted, we are surely going to have issues while logging in. In this case, we need to delete the files, and once we open the file again

Here’s how to delete them:

Very important, properly close the app and then press Win + R to open the Run dialog box.
Now execute the following command:
%appdata%\Microsoft\teams
Find and select all the files with .json extension and then uninstall them.

4] Enable the TLS feature in the Internet option

Try enabling the TLS feature in the Internet option. Doing so will prevent the device from switching off the connection by providing a secure connection during data transfer.

Here’s how to enable TLS:

Go to the Search bar, type, and select Internet Options from the pop-up panel.
Click on the Advanced tab, and navigate to the Security section.
See if TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 are enabled or not, if they are disabled, enable them.
Finally, select the OK button to save the changes.

Run Microsoft Teams to see if the issue persists

5] Disable VPN

VPN client and Proxy servers can cause hindrances in the connection between the Teams server and the Windows 11/10 client machine. As a result, we won’t be able to access Teams, so either disable or uninstall your VPN software or remove any proxy server from the device. Once done, check whether logging in to Team is possible or not.

6] Reinstall the Teams app

Sometimes the issue lies in the installation, due to which doing any troubleshooting methods other than reinstalling the app won’t work. In this solution, we are going to uninstall the app, delete the AppData folder, and then reinstall it.

After uninstalling the app, click Win + R to open the Run dialog box. Type %appdata%, hit the Enter button, and then search the Teams folders. Right-click on it and select Uninstall option. After doing this, reboot the PC, and install a fresh copy of the app.

7] Use the web version

The error CAA30194 is mainly seen in the desktop version of the Teams. Therefore, if the solutions mentioned above seem ineffective, we suggest running the web version of the app. To access this, just go to the Teams at teams.microsoft.com, log in to the account, and proceed.
