Hi
i have a error on my teamvier"Reason Unknown" Not sure what to do to fix
Please assist
Anybody figure this out yet? I'm having the same issue (also on the latest version).
I have the exact same problem (I'm also on the latest version of Teamviewer)
thanks for the answer, but even with the latest version,the issue persist
I was also getting the same error . I have installed the latest Team viewer version . Now I am able to connect to remote pc . So please install the latest version on both client and remote machine.
first try with client pc and check you are able to connect or not. if not then install the latest version on remote pc.
Hi all,
when I try to connect to my computer with unattended access I got this error message :
QuickConnect Denied Reason: Unknown issue
Anyone have an Idea about it ?
This is the first reference I have ever found as to how to resolve the Can't Connect Unknown Reason for TeamViewer 12. Everywhere else I saw an instruction to uninstall or upgrade to the latest version, but those never worked even when scrubbing the Registry and leftover files with Revo Uninstaller. In sifting through the Management Console I happened to notice that I had exceeded the number of deployments, but there was no indication that this would result in an inability to connect to newer deployments of TeamViewer Host (Quick Support was oddly unaffected). I cleaned up my deployments to get well under the number that my license supports and BAM! my Hosts could now be connected to.
I know I am on an older version, but the messaging and what I found on a web search was completely wrong (uninstall/reinstall, upgrade to the latest version, etc.), and I could have been spared hours of frustration if somewhere it was noted that exceeding the number of deployments would result in newer installations of Host not being able to be connected with the cryptic "Unknown Reason" error.
Hi @dlpastel,
Thank you for visiting the TeamViewer Community!
Would you mind sharing how did you do the computer deletion, please? Was it on TeamViewer Computers & Contacts list or TeamViewer Management Console?
The issue sounds related to Managed Devices and we suggest you check out Delete Devices in bulk if you would like to do the deletion on devices.
Kindly let me know if the Community articles help you!
Best,

I am receiving Reason unknown when trying to connect to remote computers. A couple of them work but most do not connect.
I went into my account and it said I had too many computers so I deleted probably 75 computers but it is still not working
I am unable to do remote saying connecting after that session terminated.

Hello
Thank you for your message and sorry for the late reply.
Have you tried to restart the TeamViewer service on both sides of the connection.
Please restart the TeamViewer service:
It might solve the issue.
Just installed TeamViewer 14.7.1965 on a Windows 10 client and host. I get the error:
A connection could not be established: reason unknown
followed immediately by:
The remote TeamViewer is running and old version which is out of date.
The message boxes pop up one on top of another. Both the client and host are current. Rebooting did not help.
Both myself and the person I'm trying to offer remote help to are on version 14.7.1965 and I'm getting a 'reason unknown' error saying that the remote TeamViewer is running an old version. This isn't the case. Why am I getting this error?
Same problem here. Say needs to update but after give me same error. No ideea why. I use it maybe once a month the free version.
I'm getting the same "reason unknow" message when I try to connect to my laptop from my iPad and the connection fails. this just started happening in the last week. Here is a TV suggestion to someone else having the same problem. Can you tell me how to check and open the Port?
Can TeamViewer reach the Internet?
Update - narrowed this down to MAC to MAC connections. I can establish a PC to MAC connection (and visa versa), but MacBook Air to Macbook Pro (and visa versa) triggers the "Version out of date/Reason unknown" sequence of errors. Does not seem to be TV version specific. MAC OS version is High Sierra 10.13.6 on both machines. TeamViewer version are the same on the MACs - 12.0.139437. Upgrading to TV 14 resolved the issue. Both Macs could connect to each other.
Anybody else see this behavior?
Thanks
Hello @brhuge,
I replied to your post here: Mac to PC Remote Computer "Unable To Connect Reason Unknown" Partner Still using an older version of TeamViewer
@JeanK
Main: Mac OS Sierra 10.12.6 Team Viewer Version 14.3.4730Remote: Windows 10 Team Viewer Version 14.3.4730
I've tried the Remote on Numerous Different Versions of Windows inlucding WIndows 7, and 8 as well as all versions of windows 10. None of them work and all give the same error. The weird thing is if I choose Remote Control using windows authentication and enter the Windows user name and password I am able to connect just fine.
Hello @Tatti
Could you please tell us the operating systems you are using and their exact versions, and also the exact versions of TeamViewer that are installed on your devices?
Cheers
I have this problem too. Have unintalled/reinstalled several times & tried different versions.
Hi @Yoyo2 ,
Thank you for your reply.In this situation, it is difficult to find the exact reason without a logfile.
However, you might be able to do the following checks:
Hope this will be helpful.
All the best,Yuri
I updated the version of the computer and the issue is still the same. It orginally was connecting well and suddenly the issue happened.
Thank you for your post.Could you please check if you are using the latest version of TeamViewer?This might help this situation.
I have been trying to access my computer remotely, but I keep getting "a Connection could not be established, Reason Unknown"
Both computers have the same version, so I tried to use a spare computer, the issue still persisted.
Is there any solution to the problem?
