Hello Adrian, thank you for the quick reply and most of all thank you for the app !
I created my Conexoon account (it’s a cozytech conexxon bridge for an Atlantic heat pump, btw) one year ago.
I installed the homey app last month and I saw it work properly. But I did not implement yet my Homey flows. Therefore I did not see when exactly it stopped working.
For the three server options, I get the following code :
“Error : Request failed with status code 400”.
I run the v2.1.77 version of the app on Homey Pro (2019) v 7.1.3
Just in case it might explain the situation : I had a power outage for a couple of hours, one week ago.
