OBD and Android Auto Issue

I have been using ABRP in the Pro version for many years and the live data via OBD has almost always worked when I use Android Auto and ABRP. But now it suddenly doesn't work anymore. On the phone the status is "Connected" but on Android Auto ABRP shows me "Not Connected". Something is wrong because the connection to my OBD dongle is active and data is also being transferred to the phone. I currently drive an MG5 and a Pixel5. ABRP is up to date!
