@marce  yeah tried twice.. but no luck

 

 - I ran your original client debugging output through : https://cway.cisco.com/wireless-debug-analyzer/ which gives the output shown below (Show all flag was checked), though I have doubts whether it is relevant because it is rather short. Take a longer client debug session and run it trough the same tool , also check the controller configuration with https://cway.cisco.com/tools/WirelessAnalyzer/ , for that you need the output of the running config with no promts in between :
