Hi Erik,
We're glad to look into this & help you.
From your message, it seems that few ports needs to be opened.
Please try enabling 'Internet connection sharing mode' in firewall settings & check if it helps (Open AVG Internet Security - Menu - Settings - Full protection - Enhanced firewall).
No this is not the solutions. The moment i have set internet sharing in AVG and switch AVG on as main firewall. The stream stops again. The moment i stop AVG Internet Security from being active. The music van be players again.
I made a stream from my Windows pc (Windows 10 pro) with Winamp and a Shoutcast plugin / server (DNAS) together with AVG Internet Security it blocks traffic at the port 8000 / 8001. Incomming. When switching off the AVG firewall traffic works fine. The moment i switch AVG back on the stream is broken. By a browser i can't reachthe server. The moment i switch off AVG the server is visible and stream is back again. But irather prefer to have AVG running. What needs to be set in the AVG to let it work so that my port will be visible and the stream is working
