Having the same issue with P110M. My credentials are correct but cannot add to home assistant

[ProfessorShroom]

I'm also getting this today with a P100. Credentials are correct as I logged in on my phone to make sure

[ProfessorShroom]

So the solution is to change your password to something and then just change it back to what it was. If you change it and leave it the existing plugs will stop working

[dyeadon]

Yes that worked for me. Just change it back to what you had so that it doesnt bugger up all your previous devices

[nibouk]

Changing the password in the Tapo app, and then back, didn't work for me. Had to go back down to 3.2.0.
