Fenix 6s pro Wifi 0200 error

Hi,

I try to use my wifi network for downloading my Spotify play list to my Fenix 6s  The Wifi test in the Garmin Connect app succeeds everytime I try to download my play list, connet to my wifi network from within the wifi settings of my Fenix I am getting a wifi 0200 error. I tried to change the wifi mode in my router from mixed to 802.11n, g and b. But that did not help.

I tested with another network and did also not help

I tried to sync via WIFI and also get an error

Kan someone help me?
