There are many different types of errors that can occur when you try to use Microsoft Teams. One of the most common errors is microsoft-teams-202 error code. In some cases, this error might occur because of server problems or because of problems related to the software itself. Either way, there are some solutions you can try to get rid of the error.
Usually, when this error code appears, it is accompanied with a brief detail explaining the error. It will likely say something along the lines of, "ERR_CERT_AUTHORITY_INVALID." To put it simply, this means the software wasn't able to connect you to the relevant server. This is one of the most common errors that you can encounter with Microsoft Teams.
What should you do if you get this error code? There are some steps you can take to resolve this problem. This error code usually has something to do with the SSL certificate, which is a type of certificate that is used to secure data in an encrypted format. If the error is due to this, then it is likely that the certificate is expired or it has been changed and it can't be accessed.
To resolve this issue, you should contact your IT team and ask them to check if the certificate has been changed or if there are any software updates available for the Microsoft Teams software. You can also use an SSL certificate checker found online.
Are you using a VPN or some type of proxy? If you are using a VPN or some type of proxy, then you might need to deactivate it before trying to resolve this error. A VPN, especially an unauthorized one, may clash with your Microsoft Teams. Therefore, try disabling it before relaunching the Microsoft Teams program.
