Unable to setup Plex server on Synology NAS

Go directly to the IP address of your NAS. http://192.168.1.155:32400/web.

You have to be local to claim a Plex Media Server. Quickconnect is treated as a non-local domain.

Do not use the beta version from the Package Center. It is not fully compatible with DSM 7.

Stay with the latest version from plex.tv installed manually.

Give the system internal PlexMediaServer user Full Control (not just R/W access) to the PlexMediaServer shared folder.

Read/Write is sufficient for your media folders.

Follow this document for installation of Plex Media Server on DSM 7 systems. Note that the latest beta version, 1.24.5.5160 (release notes), cleans things up a bit. You no longer see the prompt about log file location. It just uses the PlexMediaServer shared folder.
