So I set up the client’s domain subdomain to a droplet, which serves as their “backend”. I can access the website fine on admin.clientdomain.com, on mobile, browsers and different browsers or computers. The DNS is handled by digital ocean, and I have confirmed this is working.

When the client attempts to access the subdomain on a safari browser (mac computer), it just reroutes to the main domain. When giving them the IP of the droplet, it just loads a white screen. The droplet has a Wordpress site from the marketplace loaded on it.

The site is also https encrypted with lets-encrypt.

I have
1) Switched off the UFW firewall - no difference
2) Asked the client to clear the cache from their browser / try different browsers - no difference
3) Ran a traceroute from my side to the subdomain, which looks like its working fine.

The website is the default Wordpress one from the marketplace, I have the default apache2 conf, and in /var/html/.htaccess I have this (to redirect to the admin panel, as this is used as a CMS).

RedirectMatch ^/$ /wp-admin

I’m running out of ideas, besides it being an issue with the client’s ISP.

Hi @afletcher,

This sounds really interesting! I’ve just tried to :

  • Open your Droplet’s IP in the browser
  • Ping the Domain it shows
  • Do a CURL request to see the headers it returns.

I can confirm everything looks to be working perfectly well. Having said that, had you made any changes to the Apache’s Vhost files of the domain? Maybe the issue lied there.

Alternatively, my suggestion might have been a router cache as I have seen this, and after a reboot of the router everything worked perfectly.

Can you confirm what was it as this is something I would like to know as well?

Regards,
KDSys
