Hello everyone,

I’m getting this error message in QCOM = [2023-11-17_00:18:02:620] Open COM Port Fail
Qnavigator can only connect via " Quectel USB Modem" p0ort.
Any ideas? How to restore the ports connectivity?

Thank you beforehand

Check whether the COM port is occupied by another tool

Have a great day, thank you beforehand!

If your PC is Windows 11, I suggest you switch to Windows 10 and try again
