For some reason renewal of Dreamhost^[1] Let’s Encrypt certificates (as detailed here) have started to fail on my setup. Support reckon this is something to do with Cloudflare and IPv6 and asked me to disable Cloudflare for the domain in order to process the renewal. Obviously this isn’t great and so I’ve switched out my domains to self-signed certificates instead. Obviously this means having to switch Cloudflare’s SSL settings for the domain to Full rather than Full (Strict). It’s still end-to-end SSL, so the result is pretty much the same.
