PleXBMC on Fire Stick can't find server

I have Kodi 16.1 loaded on fire stick. I install PleXBMC. When I start it, I just get an error. When I go into the configuration settings and look for a master server, there is nothing in the list. I have a Windows box, and 2 other android boxes, and they find the server just fine. The first time I installed PleXBMC, it connected. Since then I got a different computer running my Plex server.
I deleted the app data and cache. Uninstalled Kodi. Installed 16.1 and installed PleXBMC. Still doesn't work.
I looked thru some threads,but couldn't find any answers. Found a few people that had the same error.
Anyone have experience with this issue? I tried to get the log file. Nothing made any sense to me. Not 100% sure I was looking at the right thing. I think I was.
