2022-10-04 22:10:29 INFO: [Tcab393f9] disconnectedCan I have access to the server to take a look?
yes. what do you need to access the server?
At least the URL and login. Potentially database access as well.
it will take me a few minutes to reinstall 5.4
to which address I can send my login details
the problem is probably with the h02 protocol
I have a second device with the gps103 protocol and it worked properly
Actually we need steps to reproduce it on a clean server. Having login and even database backup didn't help.
Hello,
I have such a mistake in my log.
Vehicle positions are not displayed on the map.
