 @sangroma Out of curiosity: How come you used a browser version from 4 years ago?

 @KristjanESPERANTO as far as i remember i installed some kind of raspbian light version because i dont need much on the device. just wanted to show the internal webpage of the docker. 
 as it got deprecated i couldnt update to a higher version. need to set up a complete fresh OS :D
