Can't connect to TeamViewer on Linux v5.x kernels from TeamViewer Insider on Windows 10

jdrch

I'm running TeamViewer Insider v15.20.3 on Windows 10 x64. I can connect to my Debian 10.2 (X11) machine just fine, but when I try to connect to my Ubuntu 21.04 (Wayland) laptop or openSUSE Tumbleweed (X11), desktop, the Windows 10 TeamViewer client connection attempt gets stuck at Connecting...as shown below:

TeamViewer has worked previously on the Ubuntu 21.04 machine before it was updated to 21.04, so I suspect TeamViewer is not playing well with the new kernel version.

I figure the difference here is the kernel versions each machine is running. The following is the output of $ uname -a for all 3 machines (full machine specs at each link):

Debian 10.2 (X11), TeamViewer connects:

Linux DellOptiPlex390-1 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3 (2021-07-18) x86_64 GNU/Linux

Ubuntu 21.04 (Wayland), TeamViewer does NOT connect:

Linux HPProBook4530s 5.11.0-22-generic #23-Ubuntu SMP Thu Jun 17 00:34:23 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

openSUSE (X11), TeamViewer does NOT connect:

Linux DellOptiPlex390 5.13.2-1-default #1 SMP Thu Jul 15 03:36:02 UTC 2021 (89416ca) x86_64 x86_64 x86_64 GNU/Linux

Any ideas?
