Hi, do you have Rename Login Page enabled? Do you have or use any services that need to access your site remotely?

Well, all services need to access the site remotely?

No, haven’t renamed the login page.

They are actually both supported and they are fundamentally different in the way they work. See this the following for more information:
https://httpd.apache.org/docs/2.4/mod/mod_authz_host.html

https://httpd.apache.org/docs/2.4/mod/core.html#hostnamelookups

The default for HostnameLookups is off. To make your config work, this would need to be changed to Double?
