Access Control changes from Full Access to Deny outgoing remote control sessions

Thanks for the clarification.

If I understand correctly - if you set the device to Custom settings, the issue does not replicate?

If no policy, and the above steps did not resolve, then we may have a unique, very specific case. In any situation, the next step would be to perform a complete uninstall of TeamViewer - If you have already tried a re-install, you may want to use the advanced steps mentioned here and ensure all files removed from the registry:

Please let me know if the issue persists!

I am glad to hear that the original issue was resolved.

For the alert message you received, could you please provide a screenshot of the installed TeamViewer?

Please also confirm this was a fresh installation from https://www.TeamViewer.com/download

The alert you received would appear if you attempted to connect to a custom module:

The resolution for such an error would be to uninstall the customized module, go to our Downloads page, and install a fresh copy of the latest version of TeamViewer.

Thanks in advance for more information.

Hi Josh. I have now uninstalled and reinstalled TeamViewer again. (The first time I did this I removed the PC from my account and proceeded to uninstall and reinstall from there. The second time, I used the download link from the uninstall page you specified. Strangely, the two setup.exe files I got were of different sizes.) Anyway, I have thoroughly tested remote control, VPN and file sharing between all of my PCs in both directions and everything now appears to be fine. Many thanks again for your help, particularly the information about removing entries from the Windows Registry following an uninstall. Regards, Ross.

Thank you for your post, and welcome to the TeamViewer community!

That is an odd one - but I think we can uncover the root cause 😅

Quick question - do you know if the affected devices are assigned to a TeamViewer policy, put into place either by yourself or an admin?

As TeamViewer policies can manage many settings remotely, this would be the first potential explanation as to what is causing this.

If you are unsure, you should be able to view the applied policy of a device in the Management Console in the group where the device resides.

Thanks in advance for the clarification!

Hi JoshP. Thank you for replying to my post. It's not a business set up and there's no admin, just myself and my Teamviewer account. I am 99 percent certain I have never set any policies or used the Management Console before in any way.

Thank you for the clarification.

A settings policy is the pretty much the only feature inside of TeamViewer that could revert a specific option on it's own; that means we will have to look a bit closer!

Can you please let me know if this device is assigned to your account in the TeamViewer General settings? If so, please unassign and then re-assign the device to your account.

Then set the Access Control settings back to Full, save the settings, and try again to see if it reverts.

Please let me know if it persists!

Hi JoshP. Thanks again for devoting your time to my problem. The device is assigned to my TeamViewer account. I removed it as you asked. Exited the Settings. Went back in and reassigned it. Exited the TeamViewer Settings again. Went back in and set the Access Control setting to Full Access. This fixed the problem, as usual. I then exited and relaunched TeamViewer and the problem recurred, the Access Control setting having reverted once again to Deny outgoing remote control sessions. I have also had a look around the Management Console but there seems to be very little going on in there.

One more small piece of information just in case it helps - if I set the Access control setting to "Custom settings" and configure everything to "Allowed", this also allows me to connect to other computers remotely. But again, when I restart TeamViewer I can no longer connect remotely. The only difference here, is that when I go back into the Advanced settings, the Access control setting has remained as "Custom settings" rather than being changed to "Deny outgoing remote control sessions". This made me wonder if I just left it as "Custom settings" rather than changing it in any way, what would happen? So without changing anything in the settings I just clicked on OK, and sure enough when I came out of settings I could access the remote computers again. Strange!

The main issue does replicate. The only difference is that the Access Control setting remains as Custom settings rather than having changed to Deny outgoing remote control sessions. Still can no longer access any other remote computers until I go into Advanced settings and click OK.

Thank you for the clarification.

It does seem that something might be controlling this specific setting, causing it to revert.

Could you please let me know if you performed a full uninstall, including going through Registry Editor, as mentioned here?

Thanks in advance!

Hi. I have now performed the full uninstall and reinstall - there was only one registry entry to remove under the headings specified. I was loathe to do this as I at least had a work around and I frequently find with TeamViewer that solving one problem creates another. First impressions are that the issue of my desktop/ethernet connected PC losing the ability to connect to remote computers each time TeamViewer is shut down and relaunched, HAS been fixed. But I now, instead, have a problem trying to connect TO this computer from others. Something which was not a problem before and is a bigger issue for me as I connect to it more frequently than from it. When I try to connect to it I receive a message saying:- "TeamViewer Plan upgrade required. Your current TeamViewer plan does not include connections to customized TeamViewer modules. Your session will therefore be terminated after a short time. Please upgrade to a higher pan to use this functionality". In fact there is no short time - it then says "Connecting" swiftly followed by "Connection not established". A connection could not be established." Do you have any idea what is now causing this please? Many thanks.

Thanks for the update @Ross_Fletcher - I am glad that we could get this resolved for you.

As always, we are happy to help!

Have a great rest of your week. 😁
