Hey guys,

I set up a Cloud Flare tunnel. The tunnel is working when I use public and domain. Everything works fine, however when I try to set up the Cloud Flare tunnel to work with the internal Railway provided domain name, then I get a 502 error. This most likely indicates that either that something is incorrectly set up, but overall everything works, so I think the issue lays in one setting not set correctly. But I followed the tutorial, and everything looked to be correct.

I think it correctly done as stated in the tutorial. https://railway.com/deploy/cf-tunnel

And as earlier mentioned, when I put any type of publicly available domain, so for example I put there https://google.com or something, then everything works. The thing is that I don't want to assign a public available domain because it's a staging environment.
