Traccar can view data, but don't update device....
In good case traccar write deviceID and additional parametrs, but here its empty. If I change deviceID in GUI, then traccar will answer "Unknown device":

I think, what url-string is correct, but don't understand how debug it... If I remove problem device and change deviceID on good device to Y-PC - it will works.
Can you help? Thanks in advance!

The issue is that you close the connection immediately.

it works. thanks!
