Cannot connect to charger all of the sudden

[WayeeWang]

Hi, I've been using this integration for almost a year, all worked fine until somewhere today.
All of the sudden all entities of Alfen became unavailable.
The integration shows "Failed setup, will retry: Error communicating with API".

I tried reinstalling the integration (latest version), rebooting HA, rebooting the Alfen CP. None of these helped unfortunately, always the same error.

Alfen Eve works fine to connect and read out all information from the charger.

Active load balancing is Enabled (as shown in the app).
FW is 5.6.0-4104.

Could you please help diagnose the issue? Many thanks!

[WayeeWang]

I'm on the latest one now (2.9.1).

Maybe try previous on 2.8.9

I can no longer downgrade to earlier versions anymore. I see it was the same in #162
