Server Version#:1.21.0-3744 Player Version#:Any So one day my server is not accessible. I get this at the login screen “This application is at 192.168.1.23 and is not hosted by Plex. Continue only if you recognize this server and wish to grant access.” When I login, i get my shared accounts but not my server. If I log into my phone, or my appletv on the same network, it sees my server and library. But off network and into remote, its not there. I googled everything and tried to delete the preferences.xml but they dont seem to show up on any system I am at a complete loss ---

It’s as if all the tech weenies decided to turn on strict DNS-Rebinding protection everywhere because they thought we would all be out drinking and wouldn’t notice. There is a lot here to unpack. Version 1.21.0-3744 and Synology, that is a pretty old version and I suspect you got hung up during a DSM6 to DSM7 upgrade.

Thanks for the reply! So, something is not lining up here. I get the uninstall screen, I get the option to keep, sign out and unclaim, or erase all data. I did the first option like you stated, but I do not know where you are getting this “Claim Code” I am not seeing that pop up anywhere along the way or within my plex. And just for shitts and giggles, I chose the sign out and unclaim, and still no resolve. ---

Installed same sdk, no option for claim code was ever given, just “install”, then installed. Opened Plex after installed, and then signed in. ---

ok, so I guess there are five different SDKs for synology… I found the one that is for my setup, I got the claim code now. after entering that in, it fails at installing with this error message "Failed to install package ERROR: Could not cmplete dialog with Plex.tv. Unable to claim. Either installation was too long or difficulties communication with Plex.tv exist. Please try again or seek assistance in our Support Forum." ---
