Overkiz (by Somfy) Integration - Failed to connect . How to debug

Hi Folks,

unfortunately my somfy roller shutters stopped working out of the blue. I was on HA 2022.3 when the error occurred but updated to 2022.7.1 now.
My gateway gets discovered automatically but I’m not able to login after clicking “configure”.
I fill out the form with my email/password and select “Somfy Europe” as Hub but I only get the error “Failed to connect” with no further information.

I also set the loglevel of homeassistant.components.overkiz to debug, but the log stays empty. The only message I get is:
2022-07-08 17:02:08 DEBUG (MainThread) [homeassistant.components.overkiz] DHCP discovery detected gateway ****-****-8878

Am I doing something wrong of is Overkiz just down at the moment?

Thanks in advance

Problem solved: There was something buggy in my DNS-Config:

~ ping accounts.somfy.com
ping: accounts.somfy.com: Temporary failure in name resolution

I found this out by using the “Getting started” example here:
