media server no longer available

Dear all,

Been using Serviio for years now, always worked perfectly and had not a single issue.
This week I changed my laptop and I installed Serviio, however, no luck with that. I have Samsung ES5500, and when i push Source button Serviio does not appear. Also, BubbleUPnP is no longer finding Serviio.
I restarted my router ASUS RT-N56U couple of times, but with no effect on the DLNA server.
I checked the firewall settings, and Serviio is allowed.
I have no idea what to do.

Can you please help me? If anyone has time, you can connect remotely to my laptop to check settings.

Thank you.

I opened my old laptop and Serviio is working just fine on it. Any ideas why on the new laptop is not working?

What are the operating systems on the laptops? If Windows, it sounds like some issue with the internal Windows firewall. Possibly an anti-virus program as well.

This same issue is happening to me, but on a Mac. If I don't open Serviio for about a month, it will work for 24 hours the next time I open the app. It won't show up under BubbleUPNP. Not sure why. Everything else seems to be working fine. Tried buying pro, thinking it might fix the issue. No luck. I can't find a way to take this thing all the way back to default settings. I'm a big novice at this.
