    I'm not sure how best to describe this, but sometimes, a client visiting one of my websites ends up on another that's hosted on my server.
    All sites on my server have LE certificates so when he ends up on a different server, there's the warning of the SSL certificate name not matching the webiste which is to be expected.
    He's seen this when trying different source IPs (on a VPN). I don't know exactly if his VPN is presenting things strangely giving Apache confusing messages and then pointing to the wrong vhost.
    His site: hdtechlogic.com
    Sometimes, ends up on jhudson.co.uk
    I've been through the Apache logs cross-checking his source IPs with the websites and everything seems to match and I cannot see anything wrong there, and as far as I can tell, DNS is set up correclty - both domains have the primary domain and A/AAAA "www" subdomain records created, all pointing to my server's IP.

    Any ideas where to look?

    Illustration of the problem.
    Client navigates to hdtechlogic.com
    But gets the SSL certificate error message because the page actually being delivered is from jphudson.co.uk
