In Mac mini Monterey. In Sys Pref, Ethernet connections, I was trying to add an exception in Bitdefender to allow a hardware streaming player called urendu to play Audirvana, a music streaming service. A window called urendu a server and ask for password. Since I could not enter the right password, I checked the read only box. Since then I've discovered that urendu can be connected to the Mac by going throuch DHCP with IP address. But I need to get rid of the read only version of urendu and I have not been able to delete it. I'm new to Mac and I would appreciate any help.
