Can't Find third server

Hello I am thoroughly familiar with how to share my server with others. And recently what started happening is that when I share my server with a plex member two of my three servers show in the list. I made sure it has remote access, shared the channels and server, but it has yet to show up. this happens about 3 days ago.

Are all 3 of your servers in the same location? Please confirm that they are all logged into the same Plex account. Can you access all 3 servers locally and remotely?
