Outlook not connecting to virginmedia.com email

I have 3 windows 11 machines.  All running the new version of MS outlook.  For whatever reason one stopped updating with new emails.  In bug fixing I decided to delete and and re-enter account.   Mail remained working on on other machines but I couldn't get password accepted on new account.  Virgin website said "new app password required for 3rd party mail applications".   I generated one but it didn't work when input. All it did was break the account on other machines. Strangely enough new password was accepted for outlook on my android mobile phone and also worked when I installed a new 3rd party email client on my windows machine, so not a password entry or configuration error.  

Troubleshooting details on outlook as follows:

{"SessionId":"608bd7e5-6dd9-ed40-a2ed-5c59065b4366","Timestamp":1761336393410,"Error":"INTERACTIONREQUIRED"}

Anybody any ideas?
