NO GPS on both Devices

[Zenyte-zz]

Hi

Model: traccar edition and Model H (bought in 2021) both flashed with Plattformio with firmware V5 Telelogger. (no compile errors)
I placed the devices a hole Day behind a Window in my office with direct sight to the Sky,
both powered with USB from Laptop or Powerbank and i get no GPS signal. Also tried in a Semi and Car

Tried everthing with the options, BT ON, BT OFF, WLAN ON/OFF, GPS ON on standby... i dont get any signal... Datatransfer to my traccar server via WLAN works perfect but with 0,0 coordinates.

PS: i found some old csv on the sd card with coordinates but this files are round about a year old (my first try at that time a year ago) so i think the devices are OK, but at the moment with newest firmware no GPS in csv, traccar or terminal :-(

Does anyone know how to fix this?
Please help, these two Devices laying in my office since a year and i dont get them running.

i´m no professional in adruino, please be patient :-)

greetings zenyte
