Local access of UniFi Security Gateway (changing PPoe settings)

Hi

I have a UniFi security gateway using the GZ Cloud Server.

I'm moving from BigPipe to Voyager in the next few days. So I need to connect locally to it when the change occurs and change the connection settings.

Has anyone connected locally before via 192.168.1.1 ?

I've tried the usual ubnt/ubnt and root/ubnt combinations as well as admin/ubnt but no joy logging in.

I have also tried my login which has admin access but no joy.

Cheers

Grant
