Linux Script using curl no longer works

Hello,
I've been using the following script on a Raspberry Pi for quite a while with no issues until now.

#!/bin/sh
i=0
while [ $i -lt 12 ]; do # 12 five-second intervals in 1 minute
  curl "http://<traccar-server>:5055/?id=<0404>&lat={0}&lon={1}×tamp={2}"
  sleep 5
  i=$(( i + 1 ))
done

Ther server is receiving but the device is showing the following the server logs:

0404	osmand	GET /?id=<0404>&lat=0&lon=1×tamp=2 HTTP/1.1\r\nHost: <traccar-server>:5055\r\nUser-Agent: curl/7.74.0\r\nAccept: */*\r\n\r\n

Also when I check the "more info" on the device the device time is incorrect but on the actual device it is correct.

Any help will be much appreciated.

Here are some server logs:

It is displaying exactly what you're sending. What are you expecting to see?
