If the answer is "Yes", then it may have happened as a result of Mod Security.
What is Mod Security?
ModSecurity is a module which protects your website from various types of attacks. Mod Security protects our website from hackers, attacks, a brute force attack, a cross-site request forgery(CSRF) and many other threats. Although it sometimes creates a problem, we do not recommend you to disable it but instead fix your software vulnerability. The reason for this is that ModSecurity only blocks your website if your software security is bad.
Disabling ModSecurity can help you determine whether your IP or your client/visitor"s IP is blocked by ModSecurity. If it isn"t the case, however, it means that your IP is blocked for a different reason. However, if you are sure that ModSecurity is the reason your IP is blocked, then contact us and we will find the exact reason behind it, in order to resolve your issue so that you will not be required to disable the module.
