I am getting this response result:
string(130) "HTTP/1.1 403 Forbidden
Date: Tue, 22 Oct 2019 14:36:24 GMT
My server's IP address is definitely on the list of restricted IPs (I have checked numerous times). My website is on shared hosting, so there is a small possibility that the IP address has been banned due to another user, but I really doubt that.
What other reason could it be?
