Status icons are grey, but should be colored
The vehicles are updating in real time, but the status icons are grey, see "2" above. (Or in earlier versions yellow).
The time or time zone on the Windows server is wrong. (in this case it was ~6:03, see "1" above, and it should be ~4:03)
Adjust the time in Windows.
This will result in a colored status icon according to "2" below since "1" is corrected to current time and 4:03:05 is less the 10 min from 4:08, see "1".
