Server timing out after installing Certbot certificates
Hi, I've installed Wordpress on a Ubuntu 18.04 LAMP setup and the site was working fine under http.
I followed the guide on installing Certbot https://www.linode.com/docs/quick-answers/websites/secure-http-traffic-certbot/ and the certificate installed okay and I got the right messages as per the guide but now the site times out.
It is working in that if I type http it'll redirect to https. But a visit to https://www.ssllabs.com/ssltest/analyze.html shows that it's unable to connect.
I've rebooted my Linode but still no joy. Any advice? I had my Wordpress URL set as http://www.mysite.com in the Admin panel (obviously my real URL) is that the problem?
