I am using alematics device and teltonika to test our server but it is Showing Online/Offline frequently.
For alematics, I could see the location and data but I checked the logs and found that soon device sent the data, server closes the connecting.
For Teltonika, I was trying to simulate it using tcp sender with persistant TCP, I can send IMEI and recieve ack, but after that server disconnect the connection., please see the logs below and sugggest where I am wrong or how I can resolve it.

Seems like your device doesn't like the response from the server.
Since device is not expecting mangoes instead of Ack :-0 from the server so I believe server is trying to send proper response but for some reason its not delivered(We double checked from the device, no ack received).
Would you please guide me based on your experience how I can troubleshoot further, there is nothing inside traccar log.
BTW our team is also Troubleshooting so if I found something, will get back.
As you can see from the log, the ack is sent. If it's not received at all, then you probably have some network issue. Maybe some SIM card problem.
Dear Anton
Good day!
Thanks for the feedback, yes you are correct that server was trying to send ACK but its getting failed. I've found that the server was configured with Domain using reverse proxy (I am not sure about its configuration as it was done by IT) which was causing this issue, asked IT team to rectify this issue and then it got resolved.
