Error Message MBB3-04

[Markir]

Hi, I'm receiving the MBB3-04 message when I try and access my BT Cloud and have seen you've been able to help others. Would you be able to help me with regaining access please? Thank you

Sorry - some mistake. I can't access it either.

Hi Markir
This was fixed by the BT support team, who privately messaged me. Unfortunately, I am unsure what they did at their end, Hopefully, they will send you a private message.
