Must have been a small server overload.
I think I should change the server hoster.
With the latest FSrealWX 3.02.2101 version, the weather data server is changed if the server is overloaded. A backup server is always running.
If you find an error, then please give me exactly about your system. Which sim (FSX / P3D / Xplane). Which connection (FSUIPC / SimConnect / FSrealWX-Bridge). Which OS.
