New Somfy Integration continuously throwing errors and not working

Since switching to the official integration away from the custom component, I am continuously getting error messages thrown and the covers being reachable for a couple of seconds every like half hour. Today I updated to 2021.06.3 but still have the same problem.

2021-06-08 13:37:23 ERROR (MainThread) [homeassistant.components.somfy] Error requesting somfy device update data: 500 Server Error: Internal Server Error for url: https://api.somfy.com/api/v1/site
