meta: part of my purpose with this site was to document things I am working on. In that spirit I figured I should document a lil challenge I had in setting up this site.
Setting up a post haven site with a custom domain seems deceptively easy - just put your custom domain name in the Posthaven dashboard and you are all set... right? Setting up my domain - I quickly ran into a problem. Namely, every time I tried to access the site I got a ERR_TOO_MANY_REDIRECTS in my browser.
After much painstaking research (Posthaven's docs are a lil light...) - turns out the issue is with Cloudflare's SSL settings. Specifically, you need to change the SSL mode from "flexible" to "full" and disable Cloudflare's SSL redirects (as Posthaven already does that itself). You can read about the specifics here: https://developers.cloudflare.com/ssl/troubleshooting/too-many-redirects/
Anyway, leaving this here in the hopes that the SEO gods index this page so that the next lost sole googling "Cloudflare Posthaven ERR_TOO_MANY_REDIRECTS" can save a few minutes.
