Cloudflare bare domain configuration
Hi folks,
Have struggled to get my bare domain and www. working with Cloudflare, have read the Railway docs, and Cloudflare ones, and have tried many different settings, have ended up giving up, and now I'm here.
Here are the latest steps I've followed, could you please tell me where I'm going wrong?
1. In Railway: add a custom domain for
mydomain.com
2. In Cloudflare: add a CNAME for Name = @, target = <host>.up.railway.app -> the name of this DNS record automatically changes to mydomain.com
3. In Railway: add a custom domain for www.mydomain.com
4. In Cloudflare: add a CNAME for Name = www, target = <other_host>.up.railway.app
After these steps, I can see Cloudflare proxy detected on both custom domains in Railway.
Both my CNAME records are Proxied on Cloudflare.
When I do this, the www. version works, the bare domain doesn't (I get 'this site can't be reached' in the browser).
I've tried changing SSL/TLS mode from Full to Flexible in Cloudflare, still doesn't work. I've tried disabling Universal SSL/re-enabling, same thing.
I only have one other DNS record, which is a TXT to auth with another service.
Any help appreciated!

I had to
1. create a custom domain in railway for my bare domain
2. create a CNAME for bare domain, pointing to the railway host
3. create a CNAME for www pointing to @
4. enable Universal SSL...

If you want both to work like that then you'll need to add two custom domains, a
www.mydomain.com one and a mydomain.com one
Although my recommendation would be to choose one of them and then have the other redirect to your chosen one, this keeps things more consistentI have two custom domains
I'd be happy to do the redirect - I have tried that in Cloudflare using a Redirect Rule - I think I must have done that wrong, as it didn't work
Oh I see now, sorry I misread π
Based on how you set it up, it should work π€
Quick side note here:
I've tried changing SSL/TLS mode from Full to Flexible in Cloudflare, still doesn't workSSL/TLS mode should always be on full when on Railway
Full strict, or just Full?
Just
Full is finecool
if you're doing the redirect, is the best thing to set up a custom domain for the bare, or for www., domain in railway?
that's completely up to you, personally I like it when websites don't use
www but that's just personal preference π€£and you set up the redirect in Cloudflare using a Redirect Rule?
also, should
Universal SSL be on?I believe so, although I'm not very experienced with Cloudflare so I can't really help a lot in that context
No, that should be turned off
ok, so I've just:
1. Removed my custom domains
2. Added mydomain.com (the bare url)
3. Added a CNAME for
@ and <host>.up.railway.app to Cloudflare
4. Disabled Universal SSL
and now none (www.mydomain.com, http://mydomain.com, https://mydomain.com and https://www.mydomain.com) of my urls are workingWould you mind sharing the domain you're using?

Seems the cause is a
ERR_SSL_VERSION_OR_CIPHER_MISMATCH, usually these resolve themselves and are usually caused by SSL cache
