Summary:

Not Acceptable! An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.

Problem or Goal: 

Faced this problem on one of my websites hosted on the shared plan on HostGator's Cpanel.
It's a question and answer website for Telecom and ICT experts, i got this error trying to post my answer to this question:

https://braindrain.expert/index.php/question/how-to-configure-traffic-policing-per-sub-interface-for-bandwidth-limiting-on-cisco-asr-router/#answer-7661


Cause: 

I contacted HostGator help on live chat:
https://gator4043.hostgator.com:2083/cpsess4074748396/frontend/hostgator/home/help.html

and this was their action and response:

"Thank you for holding, I appreciate your patience.

I checked for the server and the URL was blocked or malware attack reason. I have whitelisted the rule ID which was blocking the URLx

You can now check submitting an answer to this question"




Solution:

Apparently they said that the URL was suspected to be malware attack and was blocked, however they don't give details of the rules used to mark URLs as malware.

They white-listed the URL and i was able to submit the answer. 


Problem Solved?

Yes, but i think it's only a work around fix, and i might run into the same issue again, the best way would be if they give you access to the firewall rules/filter and you edit them.
