Problem connecting with my MPPT

Greetings,
i want to connect to my Victron MPPT 75 | 15. I tried it with my phone and it doesn’t want to pair with the VictronConnect app or in normal bluetooth settings. I tried it with my tablet and it works without a problem. I hope someone can help me resolve this issue.

I attached a video with some logs, it seems to disconnect constantly for no appearent reason.

Phone: Xiaomi 12T Pro / Android 14
Tablet: Xiaomi Pad 6 Max / Android 15

Just pulled some logcat logs, maybe someone can identify something from that. The device id is: CB:1C:28:EC:67:3C. Here is also the service report: 32 KB file on MEGA
