Are you forcing out Version 11 users?
I have a paid "perpetual" (or life-time) license for TV version 11.
It has worked well to connect to my clients with the QuickSupport agent for several years.
Lately however (perhaps 3 or 4 months?) it will not let me connect to many of my clients. Perhaps as many as 80% of my endpoints can no longer be contacted. They show up as online. They have not been upgraded to a newer version. They just give a mostly unhelpful error:
"A connection could not be established. Reason unknown."
There's a chance that it might cluster in my defined groups. That is, in the group "My Partners" I can connect to all the PCs. In the group "Small Offices" and "Joe's Motors" I can't connect to any.
I can't try every endpoint because I generally don't connect to my customer's PCs unless they call and ask me to. I can only try servers and security systems... things that should have nobody logged in at the desktop anyway.

Doing some more reading it looked like there may be an issue connecting to Windows 11 users. Or from a Windows 11 system.
A little further reading (and thinking) and I realize that's not quite the whole story since some of the machines I can't connect to are Windows 10 or Server 2016.
I do get an error in the log file of my machine:
<begin log file snippet>
2023/01/23 08:44:51.267 9708 4172 S0! TcpCarrierBase[73]::SendCompleteQueue(): No Connections, Type_Tcp, Dir_Outgoing, Ending 0, SendQueue 1, CurrentSendQueue 0, SendCache 0
2023/01/23 08:44:51.267 20912 18436 G2!! LoginOutgoing: ConnectFinished - error: ManagedDeviceLimitHardBlock
<end log file snippet>
Which sounds like my 'unlimited' connections have all been used up. I suspect that's just an error in the logging facility picking the closest matching error.
