Synology 7.2.1 Plex app won't run

2nd one

My Current DSM version is 7.2.2-72806 Update 2. Plex used to work so well and it is so frustrating that now now it won’t run

Please open FileStation

Navigate to: PlexMediaServer/AppData/Plex Media Server
Right-Click: Logs → Compress to Logs.zip

Download the zip file
Upload/attach it here.

Startup Crash.log (171 Bytes)
Sorry, took awhile to find

I had requested the ZIP of the entire Logs folder under Plex Media Server but what you have here will do.

The Preferences.xml file is corrupted.

The next step is to DELETE that Preferences.xml file.

Also, open https://app.plex.tv ,
– Go to Settings
– In the left Panel - *Authorized Devices
– Change ALLServer (dropdown)
– Find the Synology server
– REMOVE that entry. (We’ll create a new one)

Now start PMS

Give it a few minutes to startup

Open the Syno using the LAN IP address (http://LAN.IP.of.Syno:32400/web)

You will need to sign in.
It will then start the Setup wizard

CONFIRM the libraries it shows you. You don’t need to recreate the library sections. (It already knows)

Continue through the wizard until you arrive at the dashboard

Now go back into Settings - [Server] and check all your preferences.
Some will have been lost

Given this is a new server ID, go into Settings - Manage Library Access
and re-share with the user(s) you previously had.

Sorry ChuckPa, firstly I thought I downloaded the ZIP of entire logs it didn’t show up in my iMac download folder? However I tried to follow your instruction and it came back “Safari can’t find the server”

http://lan.ip.of.syno:32400/web

Also, open https://app.plex.tv ,
– Go to Settings Complete**
– In the left Panel - *Authorized Devices Complete
– Change ALLServer (dropdown) Complete
– Find the Synology server Complete
– REMOVE that entry. (We’ll create a new one) Complete

Take the actual LAN IP address of your Syno …

substitute that address in the URL example I gave.

Example:

My Syno is at 192.168.0.71

Therefore, I use: http://192.168.0.71:32400/web

Make the same substitution using your Syno’s LAN address

This URL will take you directly to the Plex.tv page to remove the old Syno entry.

Just in case you need it, here’s what my SERVERs page looks like at Plex.tv

If I want to remove my DS418j, I simply click the :x:

Where do I find and change the LAN Address. Sorry retired near on 12 years, not so tech savy

How do you open the browser to your Syno?

The address is in the browser address bar

I’m Very simple, I just tap on the DSM Icon then log in. I only use Synology for Plex and Photos. Monkey see Monkey do! Thank for your help by the way, my wife Googled you and found you are also retired and just help out for fun.
Regards,
Gary

That gives me an idea (knowing the mac is involved)

Try: http://diskstation.local:32400/web

If it argues that permission denied, there is another option

Won’t connect ?

OK, so here’s what we do.

We’re going to let the package installer do the work for you.

Here is the FAQ How-To (with screenshots)

While it’s for the ‘locked out’ scenario, it will also work for you.

Read it over. Let me know if you have any questions.

Hi ChuckPa, have done this same procedure many times however same thing happens. It looks like its going to open then just vanishes from screen

New screen shot shows that it removes link icon from screen the have to find in package centre

I need the logs.

Here’s how you should be able to get them.
( The Compress to Logs.zip )

If not, let me know (I think we found the problem)

I"ll try again
Logs.zip (2.9 MB)

@Poppy-K

Thank you for the logs.

I found the probem.

The Synology has lost its connection to the modem/router & internet.
