IP address blacklisted by ispmgr_limit_req

Symptoms

The panel and its websites are not available from particular IP address.

Cause

An IP address is blacklisted because of exceeding the panel's request limit.

Solution

First, you need to determine whether the IP address is in the ispmgr_limit_req blacklist:

ipset -L ispmgr_limit_req

If the IP address is on the list, you can remove it with the following command:

ipset del ispmgr_limit_req %IP_ADDRESS%

If you want to prevent an address from being included in ispmgr_limit_req (move it to the White list), simply add an allow rule to it in the Firewall section.
