Connect to Inverter by WIFI

We had a long WIFI outage but eventually back online with new router. Have set up WIFI system and resetup dongle (bought new one thinking old one might be broken) but unable to get Invester Dongle to connect/report with the web account reporting - still says offline.
New dongle
Wifi strength 100% according to dongle set up
Password checked
Dongle Wifi visible
Reset dongle after set up and dongle Rebooted (took 10minutes?)
Blue light went from flashing to steady blue

Any bright ideas? IS there something that i need to reset within my GivEnergy account to connect with new dongle?

An installer account.

Failing that then ask support. Its not something you can do as a user.

Oh s***, the hours i have wasted thinking i had done somethign wrong!
