Innr does not pair

I have just bought homey and bought around 16 RGBW led strips and 16 tunabe gu10 spots and some e27 smart bulbs.

I am adding them one by one and it works fine untill some point. Now homey doesn’t add any device. I deleted one device, did a reset and wanted to add it again, but that also didn’t work.
Also restarted the innr app, restarted homey completely and restarted my mobile phone. Nothing worked.

Does anyone know what the problem could be?
