This is a strange one. Last night, I decided to migrate my websites to a CentOS 7 server in London. I installed Centminmod on it and all is well. I copied the web files and the config files other and everything appeared to work... However, when a website is requested using IPv6, it returns a 403 error. This happens for all domains. It worked fine on the old server... Any idea where I should look? There's nothing in the global access/error logs or the access/error logs for the relevant site... Liam
Hmm, now I don't think it's a 403. I think it can't actually connect at all: Code (Text): [liam@maim ~]$ wget xf-liam.com URL transformed to HTTPS due to an HSTS policy --2016-11-21 15:37:42-- Products | XF Liam Resolving xf-liam.com (xf-liam.com)... 2a06:8ec0:3::1:c8cb, 185.117.22.190 Connecting to xf-liam.com (xf-liam.com)|2a06:8ec0:3::1:c8cb|:443... failed: Permission denied.

The strangest thing is that it works if requested locally on the server directly.
