As TomC-3828 pointed out, this looks to have been an issue with some Python packages. After it updated to 3.8.5 things started working again.

    @Lewis, Austin I'm also seeing this problem, for the past 4-6 weeks with Teams 1.3.00.25560. I also see this with versions 1.3.00.14051 and 1.3.00.16851 on Ubuntu 18.04 and Ubuntu 20.04, with and without destroying ~/.config/Microsoft across the various combinations.

    I suspect "ROOT-CA.crt" in the certutil command needs to be replaced with the root CA your organization uses. I tried doing this with the CA used here, but don't see any change -- I'm still unable to login with the ERR_CERT_INVALID and incomplete URL. It looks like Teams is using the electron browser, I assume for this part, but I'm not sure if that uses ~/.pki/nssdb for certificate store, or not.

    Hi @ LewisAustin-0644!

    What is your version of Teams for Linux?

    Does anyone else have the same issue in your organization?

    Based on my knowledge, the cache folder on Linux is located in “ ~/.config/Microsoft/Microsoft\ Teams\ -\ Insiders”. If you want to remove cache folder, you can try to run the following command:

    rm -r ~/.config/Microsoft/Microsoft\ Teams\ -\ Insiders

    Also, please try to install Teams insider version to see if this issue can be fixed.
