I don't see any issues in your log.
In version 5.6 I get a valid decode on all 3 device protocols, after the opdate tried 5.7 5.8 and 5.9. It looks like it's not decoding and I don't get a valid lat, lon, altitude and speed.
And all my devices Osmand, H02 and gt06 stays offline.
Reverting back to 5.6 it works again
If you need some help, you would have to provide some evidence.
This is the log from version 5.9 narrowed down to one Osmand device:

You have some issue with push notifications. Try disabling them.
Thanks Anton - it worked
What specific in the log led you to that conclusion?
You error message says where the error is coming from.
After upgrading from 5.6 to either 5.7 - 5.8 - 5.9
I have this issues with my devices - devices is a mix of OSMAND - H02 -GT06
The log is showing this:
I have been searching for the sollution and I have tried to disable the geocoding as suggested elsewhere .
If I revert back to 5.6 the problem is gone.
