It appears this issue is a common issue that many of us are currently having.
The solutions have been bare minimum through phone and by the looks of it online.
I think it's well established, the fault is in fact virgin media's network, not the clients trying to use and access it.
- There is a manual way to login, outlined in another forum by another customer saying you can use your email and password to login manually without the connect app, it doesn't however give you the domain which is required to login.

Virgin media's IT team shouldn't take pride in the fact virgin media customers with no training are smarter and more helpful than you.
It's 2022, the issue has been left for that long, the amount of users it's beginning to affect is mounting.
