Blocked from www.remarpro.com

Self-Hosted WordPress website running on Interworx based hosting platform with CentOS 6.

Problem: All websites hosted are accessible, wp-admin accessible, but when navigating to “add new” in plugins area, receiving “An unexpected error occurred. Something may be wrong with www.remarpro.com or this server’s configuration. If you continue to have problems, please try the support forums.” error.

Diagnosis:
-Checked and switched DNS/nameservers for hosting server. (Not nameservers for the websites, just for the hosting server)
-Able to resolve www.remarpro.com (66.155.40.250) but ping test times out.
-When connecting via telnet to www.remarpro.com from another IP, connected fine, when telnet from specified questionable IP to www.remarpro.com, connection times out.
-IP address is not blacklisted using MXToolbox search.
-Restarted services, tested with firewall disabled, no change.
-Add a few of www.remarpro.com’s IP’s to whitelist on firewall.

I have a hard time believing that my one IP address used for hosting websites is blocked by www.remarpro.com, but I’m running out of ideas as to what else it could be. Any thoughts?
