Strange Connection problem

strat65

Downloaded latest v15.20 for home iMac (Catalina), but cannot connect to remote Mac (Big Sur). Error: "Either partner isn't connected to the internet, or partner's Teamviewer is not running"

1. Other Teamviewer users can connect to this remote Mac
2. While on site with the remote Mac, I loaded TV on a PC laptop and then connected to my iMac at home, then did a screen share with my Mac Mini right next to it, and then Teamviewered back to the remote Mac (Big Sur) and got right in.
3. Took that PC laptop home and tried to connect, same error.

So, the fact that other's can connect to the remote Mac (Big Sur) makes unlikely port/IP issues there. The fact that PC gets same error makes unlikely Mac OS or configuration issues with the home Macs.

That I can connect while remotely controlling the home computers, but not able to connect when sitting physically in front on it has me totally baffled. Any suggestions?

I figured it out. The remote Mac was going into sleep mode which Teamviewer reports as "Partner not connected to the internet".

I found the TV doc on Wake On LAN (TeamViewer-Manual-Wake-on-LAN-en.pdf) and am now going through a Win server on that network that never sleeps to wake up the Mac. Then I'm able to connect.
