Windows 10
OBS 25.08
Custom RTMP = rtmp://localhost/live
Return "Failed to connect to server"
Ran through 'Bind to IP' options
Configured "rtmp://localhost:1935/live" - no change
Occurs in both Windows and Linux partitions on the same machine
Log files return same error (Windows log below):


17:00:15.254: [rtmp stream: 'simple_stream'] Connecting to RTMP URL rtmp://localhost/live...
17:00:15.256: [rtmp stream: 'simple_stream'] Interface: Software Loopback Interface 1 (type 24, 1073 mbps)
17:00:17.260: localhost/live is offline. Try a different server (ECONNREFUSED).
17:00:17.260: [rtmp stream: 'simple_stream'] Connection to rtmp://localhost/live failed: -2


How can a 'localhost' be offline? Is this a firewall or port issue? This issue is brand new and only began in the last week or so.

I'm testing with LiveSwitch, which is a WebRTC server network out of Canada (Frozen Mountain is the parent company). It worked fine with a localhost implementation of XSplit (I could see the local stream in browser code sitting on my website), but in the past, OBS has always run locally with no other program running (e.g. it streams quietly to itself even before I start Nginx or Red5Pro on the local machine.

As my experiment with a localhost stream using XSplit functioned correctly, I'm assuming the error has nothing to do with the server instance. But as the error presents on both Windows and Linux partitions, I'm assuming it might be either an OBS version bug or some firewall or port setting affecting both OS.

Well, possibly. But it certainly seems to be, based on the terminal output (last few lines).

I think you are misunderstanding what OBS and ffmpeg are for. OBS streams output to an RTMP server by connecting and sending data, ffmpeg receives input from an RTMP server by connecting to it and requesting a stream. In your case I think you're actually missing a server component - OBS and ffmpeg cannot talk to each other over directly over RTMP, there needs to be a server to manage the ingesting and output of the streams.

Thanks for the feedback! Let me see...

Harold is correct - when OBS is running and LSConnect - OBS do not communicate, there is no port 1935 listed on any Netstat output. (That includes explicitly defining port 1935 or leaving it out in the Custom RTMP input of OBS and/or the LSConnect command line input). LSConnect is looking to establish the RTMP connection over 1953, but doesn't do so. If, however, I open XSplit and run it on a localhost connection, Netstat does indeed show port 1935 to be open and in use, and the test server for LiveSwitch receives the stream being directed from my local machine.

Now, R1CH knows what he's talking about far more than I do, so I might be full of crap. But from my end - LSConnect is a local server instance on my home machine. It initiates a connection to the LiveSwitch WebRTC network with the initial command line call to 'lsconnect' and subsequently defines the input/output via ffmpeg.

So I'm unsure what to do with these pieces or how to begin troubleshooting/addressing them.
