Tado config problem

Hi,
nymea cannot configure tado anymore.
Somehow nymea lost the ability to configure and write into the log that it needs the api credentials first. Any clues?

I | Tado: Setup Tado account “Tado Verbindung” ParamList (count:0)

I | Tado: Sending request QUrl(“https://my.tado.com/webapp/env.js”)
W | Tado: Request error: 301 “Unknown error”
W | Tado: Not sending request, get API credentials first
I | Tado: Setup Tado zone ParamList (count:3)
0: Param(Id: “{330cad74-6f07-42ad-b226-299927c3c4f0}”, Value:QVariant(QString, “58978”))
1: Param(Id: “{cd67476b-978d-4a22-a40e-50cbc941e09e}”, Value:QVariant(QString, “1”))
2: Param(Id: “{8e86797e-5333-4428-9dba-9ed5ac243b44}”, Value:QVariant(bool, true))
