I have updated my TeamViewer to the newest version and tried every solution (i.e., un-install and re-install, restart computer, using other apps to clean out files) that I saw in others' posts. It still fails to connect to the partner's computer. I am using a MacOS 10.15.5. Doubled-checked that the other computer is connected to the internet and TeamViewer is running fine on the other end. Could someone help me to fix this?
