Tappo 110 plug

Hi can anyone advise

1 of my 3 tappo plugs went off line, i was able to reset and get it visable again in the tappo app and in home assistant.

However i can not for the lofe of me reconfigure it.

I can not remeber what information i need to / had entered in HA. Ive looked in the tappo app and in settings theres my name and my email adress and then password.

Ive teied both my name and email and usual passpword but no joy.

I reset my password, no joy, reset HA and this now meant the other 2 plugs have gone offline

What am i missing ?
