Cannot access the mod_cluster-manager page through the typical mod_cluster port 6666 in Apache httpd 2.4

Solution Verified - Updated -


  • The mod_cluster-manager page is set up on port 6666. It's inaccessible through browser though and it gives an error saying "ERR_UNSAFE_PORT"
  • Firefox is blocking the access to mod_cluster-managerpage. It is returning the message: "This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection."
