Ouch! After a good couple years of unhindered access, I’ve lost (remote) access to my RPI server. I’m guessing an auto upgrade might have disabled wireguard or flushed the  ip table rules. I should have had a secondary connection to the remote network since I did anticipate this happening sometime! Well, until I have physical access to the server, I’ll have to bank on my cold flash drive backups! So glad I have multiple accessible copies of the data files!
