New Synology Install Transcode Failed?

Plex Media Server
1

Server Version#: 7.1-42661 Update 1
Player Version#: 1.28.6106-7000
Using Chrome to play from server.

Installed Plex on new Synology.
Uploaded first movie as test. (James Bond’s Dr. No)
When attempting to play, get:
“Conversion failed. A required codec could not be found or failed to install.”
Viewing log files, seems like it’s having trouble with simple H.264
Also, analyzing doesn’t seem to help it identify cover art, etc. Sitting as a blank box in the menu.

Any suggestions?

Has the server been restarted and reclaimed since the security breech?

Your logs show Permission Denied when it tries to download the codecs.

Hi, thanks for your reply.

The Breach was on a QNAP. The new install is on a new Synology.

When I did the new install it asked for some kind of recovery key. I logged in with my Plex account and put in the key that it gave me.

I have not transferred any data, media, etc. From the old QNAP which remains quarantined.

Are you using 2FA or is something else going on there ?

Hello ChuckPa,

No, sorry, what I meant is that at one point in the installation process it asks for a ‘claim code’ and gave out a link for it. I clicked the link, got the code, and pasted it in.

Interestingly, the issue is now resolved.

The error was in the networking setup and some traffic being filtered going to the Internet. There were to blocked connections in the firewall log, however when I applied a rather dangerous “allow unfettered access to the Internet” it started working…

Is there a list of IP addresses/Domains or anything like that which Plex Server requires to operate correctly. I know plex.tv is one of them, just not sure if there is anything else…

Ok, Now I understand.

That “Plex Claim Token” is what signs the Syno into your account for you.

It talks to Plex.tv, gets the credentials from that Token (your account) and writes the needed account into into your machine’s Preferences.xml (how it knows it’s yours and claimed)

When you next start PMS, it will be 99.9% there
All you need do is open the Syno using it’s LAN IP address (http://lan.ip.of.syno:32400/web) and verify it’s there…

After that, it’s all done and back in

Obviously allow domain plex.tv
A lot of Plex exists on Amazon AWS as well.

Depending on your resolver, you’ll see plex.tv or see amazonaws.

If you want to make a firewall alias for plex,

  1. allow that alias to return replies (seems to have been your filter was too tight)
  2. adding the IP addresses you see from nslookup plex.tv,
  3. you’ll be well on your way.

From there, allow the outbound to *.plex.tv
and the return.

Thank you for the excellent help Chuck.
