I'm getting similar network errors despite clearly being connected either eith RG45 hard ethernet or wifi.
I had not used my Z11 pro max for a while and when i went on, it said subscription had expired. my other box, sub'ed the same still had a year left.
when I looked closely, the year the box seems to think it is is 2030.
I've unplugged for a couple days, multiple resets but nothing works. Any suggestions? The vendor Smartv4k isn't answering the email I did my etransfer thought.
UPDATE: I successfully shut off ExpressVPN application and all is right with the world. phew!
