SOLVED - Suddenly... no remote access to Subsonic.

[benzilla]

I've had Subsonic set up for a while and have been using it both locally and also streaming via phone, tablet, and web interface without any problems. Just recently, though (and I have no idea if it's corresponded with an upgrade of Subsonic or a Windows upgrade) I can no longer access Subsonic non-locally. Now, if I try to select the server via phone app I get the "A network error has occurred. Please check the server address or try again" message. Remotely via web http://benzilla.subsonic.org resolves correctly to my home machine's IP (like 74.177.164.182:4040) but then gives a "cannot display" message.

There's nothing awry according to Subsonic's control panel:



I checked canyouseeme and got this result:



But, out of curiosity I checked the port I forward for uTorrent and got the same "timed out" response from canyouseeme, even though uTorrent is working fine--and according to its own port forward checking that port is open. Weird.

Note #1: I turned off my firewall during all this testing, so I'm assuming that's not the culprit. Also:

I'm running Win 7
Subsonic version is showing as "4.6 (build 2583) – December 6, 2011." (Which is a little weird, since I've updated Subsonic within the last few weeks.)
Server: jetty-6.1.x, java 1.6.0_29, Windows 7 (52.2 MB / 85.9 MB)

Note #2: While digging around the Subsonic documentation, I saw the info about setting up your router to always assign a particular IP to the PC running Subsonic. I first set up Subsonic on my machine a long time ago and I don't recall ever having to do that. In fact, I don't think my old Westell 2200 will even let you do this. Is this procedure something that was recently added because of a change in Subsonic? Could that be the culprit?

Anyway, I'm reasonably tech-savvy, but network stuff is not my forte. I'm not really even sure where to go from here to begin troubleshooting. Any help would be greatly appreciated.

Thanks in advance,

First thing to try is to hit the save button in settings/network which will force an update of your SS.org address.
Any port forward rules that you set up manually in the router (for any service eg SS, uTorrent etc) requires a static IP on the server computer. However if you are using UPnP this does doesn't matter (so much) because (in theory) if your internal IP changes it will get sorted out.
However UPnP is notoriously unreliable with a number of routers eg 1 day it works next day it doesn't which is why most users manually forward the ports in router.
The utorrent port not being seen can also be a problem for you - its likely that it's incoming connections which are blocked or only tcp blocked but udp is open.

Wow, thanks for the quick reply! I did what you suggested and hit "save" in the network settings area and then, under "Access your server over the Internet using an easy-to-remember address"I got:

Status: benzilla.subsonic.org is registered, but could not connect to it. (NoRouteToHostException)

...which made me wonder about the port forwarding/IP issues you mentioned. When I went in to check in the router, it looks like the host machine IP was entered as an actual IP address rather than the name of the machine. I wonder if the router re-assigned the machine's IP at some point recently? That certainly would have caused Subsonic to not work. Why uTorrent (which was set up exactly the same way) still worked, I have no idea.

Again, many thanks for suggesting the "save" check.

I had the EXACT same problem this morning. How I fixed it was to log into my router (Running DD-WRT) and checked the UPnP settings under NAT and noticed that port 4040 was being mapped to 127.0.0.1 all by itself, so I deleted that entry and now port 4040 can be seen by the outside and I now have access to my Subsonic server. Hope this helps.

If you get Subsonic running with manual port entries, I HIGHLY suggest that you shut off the "Automatically configure your router to allow incoming connections to Subsonic (using UPnP or NAT-PMP port forwarding)" option in subsonic.

It will only confuse things...
