"server invalid" error for everything but xsusenet

I noticed that my SABnazbdplus running on my QNAP 410 (qpkg - sabnzbd shows version 0.7.20) has stopped connecting to most of my news servers.
When trying Test Server or trying to save after making changes, I get a message stating "Invalid server address"
This has happened all of my news servers but one - Shaw (news.shawcable.net), newsdemon, cubenet all give the error, but xsusenet still works fine. (which I haven't noticed in a while, most of my downloads were completing via xsusenet, but it's a free account so retention sucks) These all have been working fine previously.
If I ping the server name and replace the address in SABnzbd with the ip address I get from the ping, it works again - temporarily. Eventually I will need to re-enter the new ip since the address changes.
Any idea what I can do? QNAP is using google servers for DNS - 8.8.8.8 and 8.8.8.4, which I verified in the resolv.conf file

Hypothesis: IPv6 related?
Config -> Special: check the box of "No_IPv6". Restart and check if it works
EDIT: the no_ipv6 only seems to be for "Do not listen on IPv6 address [::1]", which will not solve your problem.
On your NAS, what is the output of "ifconfig"?
With SAB's Logging setting to +Debug, what are the first 10 lines of sabnzb.log after a start? Especially the lines with "IPv6" in them.
EDIT 2: See Shypike's advice.
FWIW: In SABnzbd 0.8.0 Beta2 this is solved in a very nice way.
Code: Select all
sander@superstreamer:~$ host news.thecubenet.com

Config->Special set ipv6_servers to 0

Ok, I have set ipv6_servers to 0, but I still get the invalid server address.
Here's the first lines of the log with debug enabled when starting up:

So Config->Special set ipv6_servers to 0 does not work? Strange. Did you restart SABnzbd / reboot your NAS?
You could try this: Config -> Special: check randomize_server_ip, and the number of connections to 10 per server. Then restart SABnzbd and check again.
I'm quite sure the problem is solved in 0.8.0, but I don't know how to get that running on your NAS. Unless you know how to install git on your NAS ...
Back to your original quote:
When trying Test Server or trying to save after making changes, I get a message stating "Invalid server address"
I checked the code, and that might be a bug in the TestServer not taking into account IPv6
TestServer says that in case of a TypeError
Code: Select all
except TypeError, e:
return False, xml_name(T('Invalid server address.'))
and a type error can be raised by a server ip address mismatch:
Code: Select all
$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> s.connect('ipv6.google.com', 80)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
TypeError: connect() takes exactly one argument (2 given)
This seems also to be solved in 0.8.0.

ok, tried setting Config -> Special: check randomize_server_ip to on - still get the Invalid Server Address message.
If it's fixed in 0.8.0, I suppose I can always just wait for it to be released. SABnzbd is functional-ish with xsusenet and ip addresses for other servers, so it's not a huge issue for now. As long as I won't have to keep changing those ips forever, I can probably wait for 0.8.0 to hit release status in git. The NAS has a self-updating qpkg - restarting it triggers an update to latest release version from github. I don't think there's a way to get it to use non-release channels though (as far as I'm aware)

That's a message from Test Server? If so: ignore it for now.
Restart SABnzbd and let it download ... I really expect that it should get IPv4 addresses and start downloading from all servers.

And? What is the result of my advice to "randomize"?
FWIW: this is how it works in 0.8.0: the quickest IP address will be found and used:
With only IPv4 working:
