Hi, This is probably a basic Question, but: I’m currently tring to install Discourse onto my Ubunut Server but I always get this Error: [2022-09-07 23_18_47-root@v2202001112289107119_ _var_discourse] My DNS Setting seem correct: [2022-09-07 23_21_59-DNS _ yayeet.org _ Ytimo.komentarhotlinne@gmail.com's Account _ Cloudflare – Ope] How do I fix this? Thanks in advance!

Nothing has worked. I have confirmed every time that the domain IS poin…

[image] Timothee: cloudflare is fine unless I turn the orange cloud off? I think you mean one of these: It’s fine if you unless you turn the orange cloud on. It’s fine if you the the orange cloud off. It’s fine if you turn the gray cloud on.

Hm, I disabled the proxy at Cloudflare but it still doesn’t work…

It can take minutes, or even up to 24 hours for the change to take effect Just wait :slight_smile:

Ahh, ok. Thank you very much - I’ll wait :slight_smile:

I see it, but the orange cloud must be disabled (gray) for the server’s subdomain (At least, at install time)
