Jami over a wireless LAN windows 10

Hi,

I am trying to use Jami on a local wireless network. I can get the machines to connect when i use LAN however when I connect to a wireless network I can’t call (yellow circle). Is it possible to call over a wireless lan? I am able to ping the other machine ad vice versa.

Thanks

I think this should be possible, even on a wireless connection. But unfortunately, I don’t know what is the issue here… Is the network restricted? (a proxy or something)
