Husqvarna automower installation error

Hi

I tried to install my Husqvarna automower in HA but during the installation process I failed to login to the the Husqvarna developer page. As a result, I got this error:

Since then, it has become impossible to install. Even when clearing the cache and restarting HA and logging into the Husqvarna dev page.
How to resolve this?
