Web interface unavailable

[houdini2286]

I can no longer reach SABnzbd outside my home. I know what you're thinking - it's a router issue. I really don't think it is. I've factory reset the thing and I'm able to open up ports for all the other various services I'm running, except SABnzbd, CouchPotato and SickBeard. Other services work fine - Headphones, Calibre, Subsonic and more. I can reach SABnzbd, but only when I use "localhost" in the URL.

When I restart SABnzbd, I get:

"SABnzbd needs a valid host address for its internal web server. You have specified an invalid address."

"uname -n" is returning mydomain.dyndns.org and I can ping it just fine.

I'm using OSX Mountain Lion. If anyone has any ideas, they'd be much appreciated. I'm left scratching my head over this. Everything was working fine for a long time using this setup.

If "uname -n" delivers an internet address, your DNS is wrong.
mydomain.dyndns.org is not your computer's address, but your router's.

Instead find out what the internel network address of your system is and use that.

[houdini2286]

But, even if I change the hostname to "localhost" or "127.0.0.1", the issue remains. I can't access remotely even though I'm forwarding the port. When I test the port forwarding it's failing but I'm confident I'm setting it up right on my router because like I said, I've had this working great for over a year and all of these other services are forwarding just fine.

I'm thinking it has something to do with the upgrade to 0.7.3, the upgrade to Mountain Lion or both?

[houdini2286]

Oh I see... if I use the local network IP (192.168.1.80), it seems to be working.

Thanks for your help. Hopefully this solves it. Strange that it would have worked OK before...

[shypike]

Normally 0.0.0.0 should work, provided 'uname -n' delivers a name that resolves to the local IP address.
This is not the case for your system.
127.0.0.1 will never support external access, it's called "localhost" for a reason

[spyder]

I just had the same problem - it's not 0.7.3 specific, it's something at the OS level. This morning I upgraded my OS X 10.6 media server from SABNzbd 0.6.15 to 0.7.3, and then upgraded from OS X 10.6 to OS X 10.8. Only after the OS upgrade did it break.

Turning off ipv6 as suggested does work around the problem, but I'm actually on a valid ipv6 network so I wasn't happy leaving it like that.

I tracked it down to the daemon option. I am using a LaunchDaemon config described in an old forum post, and added -d because LaunchDaemons load behind the login window (I leave the machine logged out most of the time).

Removing -d allows SABNzbd to load with ipv6 support, but only while logged in. When launching on boot (or via ssh when logged out) even without -d it won't start properly until I disable ipv6.

[shypike]

You can disable IPv6 just for SABnzbd (or rather stop it trying to serve on ::1).
This is done by adding --no_ipv6 as a parameter when starting it from Terminal, once.

[spyder]

yes, that's how I got it working, but disabling ipv6 seems like a pretty silly requirement for running in daemon mode (even if daemon mode is an unusual thing to do on OS X).

[edit] Just noticed the bit on the howto page about sabnzbd as a daemon not working. Odd that it worked perfectly in daemon mode with ipv6 under 10.6, but with 10.8 it's broken.

[shypike]

but with 10.8 it's broken.

No, it isn't. It's broken on your system, not on mine.
Now if I only knew what causes the difference in behavior...
