If the answer is Yes, then it may have happened as a result of Mod Security.
What is Mod Security?
ModSecurity is a module that 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’s vulnerability. The reason for this is that ModSecurity only blocks your website if your software security is terrible.
Disabling ModSecurity can help you determine whether ModSecurity blocks your IP or your client/visitor’s IP. However, if it is not the case, 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, contact us, and we will find the exact reason behind it to resolve your issue so that you will not be required to disable the module.
