SOLVED Can't change update train

[mider_]

*UPDATE* Issue was resolved, as per dlavigne's suggestion, it was a DNS issue. My ISP's DNS service was down and after changing it, my network issues were resolved.

Hi! Although i am new to the fourms, i have been using freenas 9.3/9.10 for over a year now and i have never had any problems that i could not fix myself. Until today. I am trying to change my update train and the box is empty and grayed out. (See First Attached Picture) If i try clicking "check for updates", i receive the following error: (See Second Attached Picture)

Code:

Update server could not be reached

<urlopen error [Errno 8] hostname nor servname provided, or not known>


Traceback
Traceback (most recent call last):
File "/usr/local/www/freenasUI/../freenasUI/system/views.py", line 1460, in update_check
train=updateobj.get_train(),
File "/usr/local/www/freenasUI/../freenasUI/system/models.py", line 586, in get_train
trains = conf.AvailableTrains() or []

File "/usr/local/lib/freenasOS/Configuration.py", line 728, in TryGetNetworkFile
raise url_exc
URLError: <urlopen error [Errno 8] hostname nor servname provided, or not known>

I have rebooted the system and reset my network interfaces and i have also validated my update, which validated perfectly. See my signature for my hardware breakdown.

Can you ping update.ixsystems.com from Shell? If not, verify your default gateway and DNS settings and try again.

I couldn't get this working at all, my box did not have internet access. I did a fresh install of corral and i again, did not have access to the internet. It seemed that my ISP's DNS servers were down. I changed them to google and freedns's servers and everything began to work. Thanks for your reply.
