No it's not mercedes it's o2. I've got the same issue. App works with my
EE and wifi (I have dual SIM) but when I go to o2 it says make sure you
are connected to the WiFi. Definitely o2 blocking a port or IP. It
wasn't like that before.
Same here. It's o2 issue, it works fine with every other network i.e. EE
and wifi ... I even changed DNS but still the same... Definitely o2
blocking something. Please update if you find out a solution.
Very strange, same thing happened to me today. I have dual sim. o2
doesn't work however when I enable EE it works fine or even WiFi. It
seems as if o2 is blocking mercedes IP address... It literally says
Check internet connection.
