EQS – no online radio after underground parking

Hello! My office parking is in an underground car park. I have the following problem: every time – without exception – when I leave the underground car park, the online services for music I use do not work. Neither tuneIn nor Spotify. I have to park the car, close it briefly – then everything works as usual again. What I find mysterious is that with Spotify and tuneIn the interface is loaded normally. Image and current title from the selected station in tuneIn are displayed, n Is there anyone who knows the problem? I am extremely at the bottom that I can’t hear music driving home as desired. Software status is RL_NTG_E330.602_23063AC3
