Something is bothering me after my hosting provider went from Apache 2.2 to Apache 2.4.
I had these Apache 2.2 rules in my .htaccess
order allow,deny deny from domain.tld deny from 188.8.131.52 allow from all
Those rules went to 500's with Apache 2.4 so I've studied the Apache 2.4 manual and the web and finally came up with
<RequireAll> Require all granted Require not host domain.tld Require not ip 184.108.40.206 </RequireAll>
I tested this with my own IP address and domain and this works, Apache gives a 403. However, the Apache error log is coming up with
<Thu Dec 06 20:16:51.641853 2018> <authz_host:error> <pid 1347506:tid 140612011235072> <client 220.127.116.11:42035> AH01753: access check of 'domain.tld' to /index.html failed, reason: unable to get the remote host name
What is it saying there? Also, because I have more the one 'Require not host' rule in my htaccess, it is repeating this 'AH017053' error for every entry in my htaccess. It is doing so for every file requested by the visitor, so after index.html, it repeats this error for 'index.css' and such.
I would like this error to go away but I am at my wits' end how to. Also, I wonder, if Apache still is blocking my own IP address and domain name in a test situation, what is this error trying to say?
I've read https://httpd.apache.org/docs/2.4/mod/mod_authz_host.html and I am not sure, when Apache complains about 'AH017053', shouldn't I be able to look that up somewhere?
