Hey,
I complained about error 5xx before ( https://igpmanager.com/forum-thread_2/7392#54942 )
But never got a real answer or explanation to it.
I want to prepare for the next race and it takes a long time - if it even finishes to load - to finish a lap in practice.
One of my drivers even got a practice lap without a laptime: http://prntscr.com/f90xh2
In the Developer Tools of Chrome I see a "502 Bad Gateway", "Error - Unable to load AJAX request" or something something 5xx Error (Can't remember anymore).
