Server Claim Issue

I have Plex Server Version 1.13.2.5102 installed on my Synology NAS. Eventhough i have the latest update, i keep getting notified to update the version manually. That is even not my main roblem. I have tried almost all “solutions on this Forum” to claim the Plex Server but non is working. WIll be much appreciated if someone can help me.
