Fopen(http://upgrades.schmoozecom.net/updates.php): failed to open stream: Connection timed out

Hi, had a strange issue happen to one of several FreePBX Distro machines I was updating yesterday. One of the updates did not complete and make it through all the previous updates. The log showed this:

This was performed on the commercial sysadmin module where there were several updates to be performed and I chose to perform them all at once.

2016-08-21 23:54:42: (10.13.66-15) curl Error: connect() timed out!

Now whenever I go back to sysadmin updates, I get this: fopen(http://upgrades.schmoozecom.net/updates.php): failed to open stream: Connection timed out

Also, when I go to module admin and try to check fore updated modules, I get this: Warning: Cannot connect to online repository(s) (http://mirror1.freepbx.org,http://mirror2.freepbx.org). Online modules are not available.

Updates are working fine from other FPBX servers on the same switch, the only difference being the Public IP. It almost seems like my machine is being blocked from the FreePBX Repos somehow. Is there some automated security I may have tripped unintentionally?

Nothing has changed on my box as far as DNS and network settings. I’m stumped. Any help would be appreciated.

Thanks in advance,
-Eric
