I just changed my a mesh network router eero 6+ and had issues with Plex. I am having trouble claiming my server on a Synology DS920+ running DSM 7.0.1.-42218. When I try to claim it, the icon cycles for a while and then gives me the option to claim it. I am using Player Version#: 1.28.2.6151-7000, which is I downloaded this evening.
I attempted to uninstall my PMS and reinstall. The PMS found the server, but on Server Setup I changed the name from my previous server by adding a 2, it gave the error: There was a problem claiming this server. It then allowed me to “Add Library” when the Media Library step came. After I finished it should the server with a triangle exclamation point. I ran into the claim server button spinning and then going back to the button.
