Here are a couple of screenshots of the chrome dev tools network timing tab from two isolated connections (this will only happen on the first load in a long while. Once the site is loaded it will usually load as far as expected (<1s) when refreshed)
The host is nearly free speech, server “type” is Apache 2.4 Static Content (No PHP, CGI, or Daemons), but no specific .htaccess/etc settings.
I am using this repo for letsencrypt automation: https://github.com/bearbin/nfsn-le
One of the domains this happens on: (but this does seem to happen with other domains on the same server and using the same automation repo): https://www.twoevelyns.com/
Any help of tips appreciated.
