Zoom not connecting by LAN

[DrTs]

I cannot get Zoom to connect on my Mac. I can use my older Mac, on wifi, but not the one I want to use (wired LAN). I get the message "You are unable to connect to Zoom. Please check your network connection and try again." I can use Skype or Google Meet, but not Zoom. Any suggestions?
