Raspberry Pi OS - Connection attempts stuck at "Authenticating"

MrGas Posts: 1

I have Teamviewer 15.41.7 running on my Pi and on my Ubuntu VM. When try to connect to the Pi from Ubuntu, I get the prompt for a password and then enter the correct password [when i enter a wrong one, the prompt returns immediately]. After that, the status icon goes yellow and the status stays at "Authenticating" until it eventually just fails and nothing happens. Teamviewer doesn't throw an error or anything. How can I resolve this? Please help.

Below is the teamviewer info from my Pi running Buster.

$ sudo teamviewer info

    I am having the same issue, did you ever find out what the solution is?

    I also have the same issue, but with a Linux Debian distro running on a small in-vehicle single board PC (not a Pi). What we discovered was that we needed an external display connected when the system is booted in order for TeamViewer to run. I think it has something to do with the device not loading the GUI when there is no need to, because there is no display connected. The second we connected a display, TeamViewer allowed the connection with no issue.

    Do you have a display attached?

    Also, I'd like to know if there's a way to force the GUI to load, but that's more a Linux question than a TeamViewer question; I'm investigating this in other forums.

    It seems that this issue is quite topical. I also cannot access my Raspberry Pi TeamViewer host as of January 01, 2024. My Managed Device raspberry is online. However, it is not possible to establish a connection. Does anyone have a solution? I found the following information in another thread.
