New PC with New Plex Server and my Roku will not connect - please help



I have purchased a new PC to purely run Plex Server and Movies. The Problem is my new Roku TV Box will not connect to the new PC. Will only connect to the Old Notebook. What am I doing wrong?


Turn off require secure connections on the Roku under Settings > Advanced > Allow Insecure Connections. Also see Settings: Plex for Roku. Make sure your Plex media Server and your Roku are both logged into your same account at Plex, which will help the Roku discover your Plex Media Server. See Sign into your Plex account.
