Serviio for Mac stoped working after 5 minutes

Hi, this is really strange. I installed Serviio and added some folders with videos. I ran a DLNA client on my iPad, and it found Serviio immediately, and I was able to watch the videos. 5 minutes later, the iPad wouldn't find the server anymore. I went to my Mac and I found the server stopped with this error " Cannot connect to the server, it doesn't seem to be running". I quit Serviio, and restart multiple times with the same error? what is wrong?
I uninstalled Serviio before because I ran into exactly the same issue a month ago.Reinstalling it in the past solved the problem temporarily for another 5 minutes, and it goes back to the same error without a reason. Anyone can explain?
Thank you
