Custom domains can't be reached after adding cloudflare proxy

[royal berry]

I just purchased a domain on cloudflare and added it on my service on railway. I added the DNS record on cloudflare, and it now shows "Cloudflare proxy detected" in railway. However, I don't know which URL can now be used to access my APIs. (If I turn off the proxy from cloudflare, I can make API calls using my newly purchased domain, but I want it to be enabled)

Can you show me your SSL settings on cloudflare?

[royal berry]

can you walk me through where to find them ?

this is my first time using cloudflare

I remember choosing always use HTTPS and switch HTTP requests to HTTPS somewhere though

[wise sphinx]

On cloudflare, select your domain, then on the left side of the screen in the menu, click on SSL

[royal berry]

it's set to flexible

[wise sphinx]

Set it to FULL

Not FULL (STRICT)

Third option down

[royal berry]

okay done

it now shows "Waiting for DNS update " in railway, but I can call my backend using the custom domain

[wise sphinx]

That's fine, it just needs to update on their end

So, you can access the domain now?

[royal berry]

is it possible to use a subdomain, for example instead of domain.com, backend-service.domain.com ?

[wise sphinx]

Yeah, you just need to add the cname for it

Just like you did the root domain

[royal berry]

yes, I can safely remove the generated railway domain I think? And anytime I make a request usingmy custom domain, it will first go through cloudflare, correct ?

[wise sphinx]

Yup

That is correct

[royal berry]

okay thanks, appreciate your help
