I can access the local network from my computer and it works without any problems, however, when I try to open a network environment to transfer a file from a shared folder on some computer, I get a 1231 "Network folder not available" error. I get the same error when I enter the computer name or IP address in the address bar on the left pane.
It used to work fine. What am I doing wrong? TeamViewer latest version 15.15.5, Windows 10 Prof, the local network is the simplest, organized by an unmanaged switch and router, distributing addresses via DHCP. I have administrator rights on the computer and network.
