All of sudden, "No compatible Streams" on all media

[maiX 0]

So, i was watching a video via emby webbrowser, and like ~25 minutes in the stream stopped and showed "no compatible streams found". I've checked, and found out almost none of my videos are playing anymore! (Videos, that were ALL working like an hour ago). I was still on Version 4.6.6.0, so i've updated to 4.6.7.0 but no luck - same issue. Restart Emby.Service and Ubuntu-Server, same issue. Seems like ffmpeg has an error, but it appeared while streaming a video?

The client is requiring a transcode because of audio/subtitle codec incompatbility.

But you are getting port mapping (upnp) errors and ffmpeg start errors.

The trancode is okay and was working well, most of my files need transcoding before playing.

The question is why does ffmpeg failes and how do I fix it:(. What surprises me the most is that it litterary happen while streaming a Video.The stream just crashed and gabe me the "no streams available" error.

holy sheet, thanks for the hint @rodainas.

Since i don't need the external access, i've disabled it to get rid of the upnp errors, restarted the servers and now everything works again. 

 

Thank you for pointing in the right direction!
