### The problem
Hi,
I am not sure if it is the right place to report this kind… of issue !
I have a authentification failed message when trying to connect to vesync integration !
My app is connected to my device , as well as Alexa and Google Home, but not able to log on with homeassistant !
On google for instance : the connection server seems to be server3.vesync.com



any idea why this is not working ?
Best
Alain
