The only difference I have found is that curl closes session immediately after http response HTTP/1.1 200 OK content-length: 0
but browser stays connected for approx one minute
I have tested your curl command and it works fine for me.
Yes it really works from but only from some computers. There is any problem with timing... The problem is that the curl and wget closes session immediately and traccar doesn't parse coordinates and doesn't write them to the log and to the database. If there is some delay it works. I solved it using telnet. Here is sample part of working and not working bash scripts (the only difference is sleep 1 after http GET)

You mean HTTP/1.1 200 OK content-length: 0 ?
I get it

Also telnet doesn't work if there is no delay after
The same result with fetch....
If the session is closed too quickly, the coordinates are not calculated. Only status of device is updated.
IT DOESN'T WORK

Today I found that it works when geocoder disabled. If geocoder is enabled and I use curl or wget or something it doesn't work.

It must be related to some timing. I set up the traffic shaper on the wan interface of the Linux machine with curl (Mikrotik router with GPS). Speed limit 8kbps for outgoing traffic. Coordinates are now written to the traccar database successfully on the Traccar server. If I disable the shaper traccar stop save records to the database immediately.
It seems that traccar doesn't save coordinates if the answer from geocoder came later than device is disconnected.
If geocoder is disabled it works with or without shaper correctly.
Traccar server ignores the same url transmitted by Curl or Wget but it accept this url why you fill it to the browser (Firefox/Chrom). I have no idea how to solve it. I need to transmit the url from bash script. Thanks for help
From Curl
from browser
