Getting 'WS login failed [406]' after a while

Hi there…

I have two Ewelink accounts with the different credentionals that controls my two houses. Each Ewelink account is entered in the Homebridge Ewelink plugin installed on two separate Homebridge instances in the same Raspberry Pi.
The first Homebridge instance is installed on the Raspberry Pi, and the second one - in the docker container.
The problem is: the first Homebridge Ewelink plugins works perfectly within the years, but the second one (newly installed) loads normally and works, but after some time starts reporting “Authentication Failed”:

And after Homebridge restart ewerything repeats again…

Plaesa, advise…

I think it’s better to ask the HomeBridge developer instead of eWeLink, but i guess there is some thing went wrong when it’s run on the Docker.
