WordPress Whoa's With SiteWorx

Hello everyone,

I have an InterWorx server running for a few small web/e-mail customers.
Amid a simple DNS issue with our ISP not resolving any domains, we changed the nameserver's in /etc/resolv.conf (CentOS 6).
Great, our websites and e-mails resume normally.:D

Following shortly after, checking on the hosted websites using WordPress on our InterWorx server, none will update or list plugin's from wordpress.org.
Diagnosis:
-Checked and switched DNS/nameservers for hosting server. (Not nameservers for the websites, just for the hosting server)
-Able to resolve wordpress.org (66.155.40.250) but ping test times out.
-When connecting via telnet to wordpress.org from another IP, connected fine, when telnet from specified questionable IP to wordpress.org, connection times out.
-IP address is not blacklisted using MXToolbox search.
-Restarted services, tested with firewall disabled, no change.
-Add a few of wordpress.org’s IP’s to whitelist on firewall.

Further searching lead to the WordPress requirements of:

• PHP 7 or greater
• MySQL 5.6 or greater OR MariaDB 10.0 or greater
• The mod_rewrite Apache module
• HTTPS support

Currently my InterWorx version 5.1.52-1311 shows installed:

• phpMyAdmin -> 4.0.10.17 (Current latest 4.7.3)
• PHP -> 5.6.17 (Current latest 7.1.7)
• MySQL -> 5.5.47 (Current latest 5.7.19)

:eek:
I checked the "Software Update" section of "Server" in InterWorx with no updates available. Is there a particular reason why it looks to be so outdated or if I should be updating it outside of InterWorx?
Thanks.
