Server Version#: 4.57.4  
Player Version#: ?.?.?

No matter what core I use and no matter what the platform, all I can get with Plex Arcade is an error message telling me that the core mapping isn’t there.

I’ve added the cores to the “Game Cores” file and updated the RetroCores.xml file accordingly.

What else could be wrong?

Please provide your xml and a screenshot of the core files.

Ah, those are windows dlls and you’re running on OSX.

You could look for the corresponding dylib files (which are the OSX equivalent files) but it’s generally just much easier to use core manager (I think there a stickied post for it) which handles the job of finding the right core, putting it in the right place and updating the xml file.

That’s actually Ubuntu (Linux) but it’s running the Windows version of Plex Media Server via Wine.

At first I thought that this was the issue so I tried the same cores on an actual Windows machine running Plex Media Server… still no go.

Apologies, I can see that now. I hadn’t realised just how close the UIs had become over the years (I’ve not run a windows manager on a \*nix for a long time now).

You were pretty close… but for the record (incase anyone else stumbles on this post looking for an answer to the same issue)… the location is:  
`C:\users\ericfledderman\Local Settings\Application Data\Plex Media Server\Plug-in Support\`

However… now what I’m getting is “Network configuation prevents direct connection to game session”

Any ideas on that one?

Huh? What you put is the same or are my eyes bad?

Do you have remote access enabled and working properly? That is required.

My fault… check the directory location in my previous post… I edited it.

Yes, remote access is enabled.

The log shows the playback errored out, but not the error itself. It’s likely an issue on the client end. From what I could tell you were trying from Plex Web on another local machine. That right?

I’m not familiar with running Windows through Vine so I don’t know if that might be the issue. I’m checking around with others.

OK. We think it has to do with running Windows through Wine. This is not officially supported so YMMV in getting this working.

The error is likely coming from the Web client. It is using a local IP address, but it is unable to connect to the server locally. This points to some networking issue.

When your stream from your server through that same Web client, does your PMS dashboard show that it is a local connection?

I assume that you mean streaming a video of some sort, however **yes** it does show as local.

Ok

- enable debug logging in the Web client
- stream a video
- let it play for 30s
- play a game
- wait for the error
- grab Web logs
