Invalid_grant trying to add l510 bulb to TAPO official app

Hi

I’m getting an “Invalid_grant” trying to add an L510 bulb to the TAPO official app.

I’ve tried using the Web app and the Android version; both give the error. I’ve tried at various times, as I’ve seen some comments about TAPO’s servers being overloaded.

Just to add, I get the same error when adding a power plug

I’m running v2.1.16 of the TAPO app on a Homey Self-Hosted Server.

Thanks

Stephen
