OK, so Web Display was unable to connect to PF3 this time - there are several possible reasons:
1) PF3 was not actually running at this time, or was not connected to flight sim (so port not open)
2) PF3 was running, but PF3 Display was already connected and using port 1010
3) PF3 was running, but on a different IP address (although, looking at a previous screenshot, I think this is unlikely)
Please could you perhaps try again, first making sure that PF3 is running and connected to FS, but without starting PF3 Display.
If you then get the 'Listening on ...' message, please can you try opening the web page from your browser (
http://10.0.0.50:7339/) and see what happens.
It would also be helpful if you could attach the PF3 Debug Monitor log from when you try this.
Thanks, Martin
