Hey @reveil, sorry for the delay here! You’re correct about Cloudflare’s SSL certificate messing with how we generate certificates on our end (discussed in another thread). So yes, you can use Cloudflare in “DNS only” mode and it’ll all work fine.
But if you’d like to use Cloudflare’s proxy services with us, we’d need to manually add a custom configuration specifically for your domain on our end. We can do this, but would require an additional one-time fee (per domain) for the engineering time it takes to set this up and maintain it. I’ll respond to your email and we can figure out if this is something you’d be interested in.
