Feature Description

max_connect_errors is used to set the maximum number of interrupted connections allowed for a single host before it is blocked. This parameter is mainly used to prevent a large number of connection requests caused by malicious attacks, misoperations, or network failures. When the number of connection errors for a host exceeds the value of max_connect_errors, the server will add the host to the blocklist and deny its further connection requests until the time set by connect_timeout is reached.
