OSX Server: Can't get Plex Connect to work

Dev Community Apps & Creations
21

Same problem here. PlexConnect doesn't work because I'm running OS X Server (10.6.8).

:(

OSX server is not officially supported yet (mainly because none of us run it to test with) but the answers to your problem appear to be above:

  • You must either disable the web server, using chrisallen's instructions in the post above you, or change the port it uses to e.g. 8080
  • Add an additional primary DNS zone on your OSX Server named "trailers.apple.com" and a new host entry "trailers.apple.com" in the new "trailers" zone pointing at the IP address of your PMS

EDITED: to include Longariva's additional information in post 23. 

22

I'm having the same issue, and I'm using a mac mini running regular Mountain Lion.

"[Errno 48] Address already in use"

Edit: It seems to be because my computer wants to run two PMS python servers simultaneously. If I quit them it works, but of course they both pop up again.

23

You can simple add an additional primary DNS zone on your OSX Server named "trailers.apple.com" and a new host entry "trailers.apple.com" in the new "trailers" zone pointing at the IP address of your PMS.

Simple as that

Have you tested this as working?

25

If I'd known OS X Server was going to cause these problems I'd never have installed it.  Methinks when we move into our new house and the home cinema finally gets done I'll be wiping my drive and installing vanilla Mountain Lion (or even Lion)...

26

Have you tested this as working?

For sure!

27

How exactly do I add the host entry pointing to my Plex Media Server and do I need to add the PMS’s port number as well?

For sure!

better explanation would be helpful, as PlexConnect still tries to create the dns server which it can't, and adding a primary zone you can't simply add a host as it prepends it?

With very little python knowledge you can comment out the part which calls the DNS service object in PlexConnect.py.

And for the DNS Server it is really that simple as creating a zone named trailers.apple.com and in there a host named trailers.apple.com (in fact the domain part is the same as the host address without prepending a hostname) pointing at the IP Address of the PMS server. There is no magic and as Apple uses the widely used bind name server you can also edit the zone file directly ( /var/named/db.trailers.apple.com ). There's plenty of documentation for bind DNS online.
But maybe it could be a good idea to wait for a more stable/elaborated release ;-)

If you don't wanna mess with Server and you have a spare pc, run PlexConnect from there. PlexConnect doesn't have to be run from a machine that is running PMS.

31

This still doesn't tell me exactly how to make those changes; I don't know which type of record (Alias, Machine, or Service) I'm supposed to add. Messing with DNS stuff without fully understanding it is probably not a good idea for me. So I'm going to leave it alone until an updated version that's fully and automatically compatible with OS X Server (10.6-10.8) is released.

OK well I'm trying from another Mac on the network and my Terminal output is this:

Which seems wrong but nearly there as Trailers still not showing PlexConnect.

Ok, I think I have sorted out the DNS stuff in Mountain Lion OSX Server. Pings and traces resolve to my PMS IP. How are you guys running the PlexConnect webserver? Are you disabling the OSX Server Webserver? Would be great to run it within the OSX Server Webserver if that makes sense. I was also able to comment out the DNS server lines in PlexConnect.py without any issues. Just need to sort out the webserver now.

Edit - Seems not all is well. Looks like this edit has killed every other apple.com request. trailers.apple.com works as expected but all other requests with apple.com fail to be forwarded.

Change DNS Setting in aTV?

I found the answer. I hadn't changed the DNS on the AppleTV to the IP address of the other computer that I was running PlexConnect on.

But I have a strange issue. I have all 3 seasons of Game of Thrones but when I select Season 3, it says "Trailers are unavailable" but Season 2 and I work fine?

Funny, i have had the same error with Season 2 of GoT.
I deleted the Special Episode (You Win or you Die - S02E00) and started a Deep Scan.
After that, the Problem disappeared.

Strange since every other Plex Client shows the GoT Season 2 with the first Special Episode just fine.

I'm on a iMac mini Server but I'm not running an OSX Server, I'm running an OSX 10.8.3

Although I'm getting the same errors

Can anyone know what could be this error !?!

I'm on a iMac mini Server but I'm not running an OSX Server, I'm running an OSX 10.8.3

Although I'm getting the same errors 

PlexConnect : PlexConnect
PlexConnect : Press ENTER to shut down.
PlexConnect : ***
PlexConnect : IP_self: 192.168.1.121
PlexGDM : ***
PlexGDM : looking up Plex Media Server
PlexGDM : ***
PlexGDM : servers discovered: 1
DNSServer : Failed to create socket on UDP port 53: [Errno 48] Address already in use
PlexConnect : DNSServer not alive. Shutting down.
 
Nothing is using port 80, as you can see
 
Can anyone know what could be this error !?!

The error is not saying port 80 is in use, it is saying port 53 is, which means you have an existing DNS server running on the box.

it's the OSX Server DNS server, it tells you how to handle it in the "Best Answer" post.
