Error message says host not connected to the internet or TeamViewer not open. This is not true. Can anyone help me? I operate the client and I'm 25 miles away from the host. We're both on Mac Big Sur.
I recommend restarting TeamViewer on all impacted devices.

I've restarted TeamViewer on all devices multiple times. I also uninstalled and reinstalled TeamViewer on all devices, to no avail.
Unless you have something new for me to do, I have no choice but to abandon TeamViewer for a more reliable program. That's sad, because it worked magnificently for a year or more before this happened.
I'm really discouraged and hope you can help me.
We could not reproduce the error on our test devices.
It is most probably a bug on your device(s).
But I might have a last resort solution for you...🧚♂️
There is a specific way of uninstalling TeamViewer (the so-called Manual Uninstallation) that really "erases" everything about TeamViewer on your Mac.
This could reset the settings and solve the issue. It might be worth giving it a try.

I hope this will fix the issue!
Thanks so much. I just used the uninstall button on the Teamviewer from my apps folder, so I believe my uninstall wasn't complete. Will use the steps in this article and give it another try.
I am experiencing the same issue after upgrading my remote control computer. Did this fix the problem on your Mac?
Haven't have time to do a complete uninstall/reinstall. My host computer is 25 miles away from my client. Will get over there on Thursday (7/22) and report back.
