@daveabraham Thanks for this comment. I had been searching for a reason my teamviewer wasn't connecting to most of my clients since upgrading to Win11 release preview. I've been resorting to our backup remote connection while I figured it out. I had the same behavior as described above. Sometimes I could connect and see my desktop, but couldn't click on things. Other times I wouldn't fully connect. (I was thinking it was a display driver issue but apparently not)
Turning off UDP fixed my issue. I never tracked down why some connections worked (about 20%) but most wouldn't. I never could isolate what was similar on the working connections.
Thank you so much for providing this helpful information, @daveabraham . We are looking into the problem and try to provide a hotfix version as soon as possible.
I have some similar problems, I can connect to my remote windows 11 Pro updated PC, I can logging with some difficulties and when I get to the desktop, when I clic on windows menu, start menu doesn't show, and taskbar display weird things.
Tell me if you want something to look into thing matter.
I have a free account so I can look after my families PC , TV have locked my account thinking Iam commercial but Iam not using TV commercially. Help how do I get to use my account again?
short update to the connection problems.
According to our analysis, the problem only occurs on machines with special networking adapters and using UDP.
The problems are related to some issues 'between some Intel “Killer” and “SmartByte” networking software and Windows 11'. Microsoft has announced a fix by an Windows Update planned for the 12th of October.
Please read https://docs.microsoft.com/en-us/windows/release-health/status-windows-11-21h2#1699msgdesc for some more information.
To solve the problem for TeamViewer on Windows 11 for the moment, please disable UDP in the options (Advanced > Advanced network settings > Use UDP (recommended)) until you are using the new Windows update (and please remember to enable UDP after that again).
Advanced > Advanced network settings > Use UDP (recommended)
If you encounter any further problems, please post them here.
Sorry for the inconveniences.
I noticed the mouse is out of position when clicking on task bar and some 3D aplications just give a blank screen
When trying to disable UDP. I go to the options menu but TV crashes as soon as I clock the options link. It does this also when I establish a new connection to a client.
I have my log file if you need it.
Can confirm, disabling UDP corrected issue.
Using the latest 64 bit version of TeamViewer on all computers...
Connecting Windows 10 computers to a Windows 11 computer
Connection is fine if both computers are on the same internal network...
Connection is made from an external network, but there is no interaction with the Windows 11 computer...
Having an issue in Windows 11 using Teamviewer 15.22.3 C. I open up teamviewer to get started and any time I try to open a menu option or open a connection, Teamviewer closes itself. I converted tmy log file to a pdf so you could look at it.

Thanks a lot,
I downloaded todays Win11 updates and rebooted. I then turned UDP back on within TeamViewer and I was able to connect to a computer I had a known issue with...so problem seems resolved at this point. I'll update if I encounter any connection problems with UDP on.
Hi there. I just loaded the latest version of TeamViewer on my new PC with a new Windows 11 install, in order to join a meeting and view someone else's screen share (on Windows 10). I wasn't able to see anything but an empty grey screen. I requested they make me presenter to try to share my screen, and when they did, I received no notification to assume the presenter role. When I created a meeting myself and invited them and shared my screen, they also could not see anything but a blank grey screen. I just checked the latest Windows updates and will test more soon, but I wanted to share my experience. Thanks!
I tried to connect to a Win7 computer (ya I know, luckily it was with the intension of moving some old software off of it) after my previous post and had a similar issue so I turned UDP back off for now and that fixed the issue. So maybe it's only partially fixed by Microsoft.
Hadn't used TeamViewer for a while. Went to help my EX the other day. Disconnected.
Tried to reconnect, said I was not permitted and had to wait until TIME(+1min). Waited... Then tried to reconnect. Got another message to wait another minute.............?
Is this a Joke??😡
thanks a lot for sharing your experience!
If you want to, I can arrange a ticket so that you can send us your log files for the Win7 computer to check if it's still the same issue...
When i logged in to my server home, after a few seconds the session disconnect.
It said that I use team viewer for commercial purposes, which I do not.
I manage my servers at home with the account.
So what have i to to?
It's one of my unmanaged customers so was probably just a one time event connecting to that machine. I turned it UDP back on so I could watch for other occurrences. I use a Dell WD19 Docking station and a Dell Precision 3560 Laptop. I've noticed the issue when using the docking station which uses a Realtek Network card. I'm not aware of any Intel “Killer” and “SmartByte” networking software on this laptop, so I don't think the problem is exclusive to that.
Not sure if it is related, but on a laptop with a new Windows 11 install (no upgrade), after a connection to a Windows 10 machine and subsequent disconnection, the laptop will never turn off its screen nor will it sleep. I am pretty sure it is related to TeamViewer because if I stop the TeamViewer service the laptop will turn off its screen and sleep in accordance with its settings. I have installed the Microsoft Oct 12 update, but after that and after unchecking UDP, the behavior is the same.
Hi @jshulters, thank you for reporting this!
We looked into the issue but were unable to reproduce this behavior - does the issue still persist for you?

I have been locked out for so called excesive use. I have been trying to log into my parents computer to fix something, but the problem as been at there end for me to log on to team viewer not mine. Now that i want to log in, teamviewer wont let me
Using it for personal use but it's keep blocking me and insisting to buy.
Why called it Free? How can I removed this restriction?
I have been using Windows 11 and Teamviewer with no issues at all since august, until now ...
I installed the latest 'Windows 11 Insider Preview 22478.1000' today, and I am now unable to remote control anything ...
I can try to connect to a computer, but the remote screen never shows up. I have tried to control several different machines with different OS and I have tried to disable UDP, but I'm not able to use teamviewer from this machine anymore 😓
i have the same issue on two diffrent machines with that Windows version.
I have the same problem with version 22478.1012 😪
same problem with version 22478 😥
Thanks a lot, to all of you who already tried out TeamViewer on Windows 11 and for providing feedback. You´ve been incredibly helpful in the process of announcing full support. Thank you!
I am happy to inform you that now we have announced full support for TeamViewer 15.22 on Windows 11.

i have some trouble about windows 11 version
i create a new post
my windows 11 version: 22478.1012_rs_prerelease
I've got the same issue with 'Windows 11 Insider Preview 22478.1000'. I've tried remote controlling a system beside me and on that machine I can see everything happening, but the view of the remote machine is not appearing on my system. I've tried disabling UDP but this has no impact, the screen stays the same.
