Is setting up Cloudflare feasible for you?

You're encountering a Railway limitation, can't go around it with something infront unfortunately

I am not familiar with it but yes I can learn it

if you have a link to a ressource or just the name of the service in cloudflare i can use to solve this issue I would appreciate it

I am thinking about having something that accepts the HTTP POST request and transforms it into an HTTPS POST request so railway can process it and read the body

Here's what should work

• You'll have to onboard your domain into Cloudflare, you can upload a zone file etc to keep your current DNS records, docs on how to do that
• For the CNAME pointing to the service that you need HTTP on, you need to enable Cloudflare proxied and make a few rules Cloudflare may automatically rewrite HTTP into HTTPS, with the same limitation as Railway, you can disable this by creating a configuration rule (see screenshot 1) Then create a redirect rule with it configured something like screenshot 2, make sure that you select the 308 status code

Rules can be created from here in the sidebar

Thanks ! I will look into it now

Feel free to @ me if you're stuck with something

Listed 308 here, should use 307
