Why does my PC running PMS keep showing as offline?

Hello. I am running the Plex Server software on my Alienware Alpha r1. I had been accessing it from an amazon firestick on my home TV. I don’t have it set up for remote access, nor do I really want to. I’m just using it to stream my media throughout my house on my network.

Anyway, everything was working perfectly well on it for about two weeks when I set it up in early January, but now the server is showing as offline from any of the various apps I use to connect to it. The only way I can get it to reconnect to the firestick is to restart my computer. It will work for a couple hours, but then it goes back to saying the server is offline.

My PC is still online, still on the network, and still running plex, but I can’t figure out why it keeps showing up as offline.

Anyone have any advice?

Another item to check is to ensure your PMS host isn’t set to sleep, hibernate, or enter standby/powersave mode…including the network card.

Making the IP address static fixed the issue perfectly. Thanks so much for the prompt response.
