Cannot access EV charging station Control Panel after firmware 2.0 update

Today I updated the EV charging station to firmware 2.0. The Cerbo GX was already running v3.50. I did this via the Frimware Update option in the Device list from my laptop. It took 3 attempts but then everything seemed to go fine. No obvious problems except - if I attempt to access the Control via the button on the charger in the Device list it opens a new tab ‘https://216320-evcs40.proxyrelay1.victronenergy.com/login.htm’ and then hangs. If I try 192.168.1.144 via my browser then same screen, same result. Pages trys to load forever and fails.
Any suggestions? Anyone else finding the same issue? Not sure if it’s a bug in the new version or …??
