Vpilot No flight plan was found on the server

When I open vpilot, open and fill flight plan, press fetch from server, connect the server, and press fetch from server again, it says “No flight plan was found on the server” and flight plan isn’t updated. What am I supposed to do?

You are supposed to go to https://my.vatsim.net/, Flight Planning, File a flight plan.
Only then you can fetch from server (which you don’t have to btw)

Direct link to it: https://my.vatsim.net/pilots/flightplan

Or you can file it from within vPilot, after connecting.
