may i ask why the proxy manager was used?

wdym? i was searching a free way to host Nginx Proxy Manager and some people suggested me to use railway so i did and made it with the template

right but I never understood the purpose of that template, what does it help you achieve

nginx proxy manager is just a nginx reverse proxy, but with an user interface
can be used to point the domain to another ip/hostname

for example on the proxy

• [example.com](example.com) could be pointed to 12.34.56.78:5000, then https://[example.com](example.com) would show the content of [http://12.34.56.78:5000](http://12.34.56.78:5000)

• [abc.def.com](abc.def.com) could be pointed too [my.hostname.com:30158](my.hostname.com:30158), then https://[abc.def.com](abc.def.com) would show the content of http://[my.hostname.com:30158](my.hostname.com:30158)
  (including they paths)
  and both domains pointed to the same ip address

but what are you using it for? for some reason I have a sneaking suspicion that there's a better way to do whatever you're doing

cause the host i use for some of my sites use urls such as [catfein.alfari.id](catfein.alfari.id):PORT
and i want to link a domain to them
an example http://catfein.alfari.id:30009
which is an instance of NTFY

then im not sure where nginx proxy manager comes in to play here, can't this be done with cnames in your dns provider?

i think you could use caddy for this

true, but with the information I'm given I don't currently see a need to use a reverse proxy

i can use CNAME in some of my domains, but not all since some of them have other records

i can use CNAME, A, AAAA, MX, TXT, URL (redirect)

so on some only IPv4, IPv6 and some other can sue the cname

okay, well in that case, railway does not have a static IP, you can't use IP addresses, you need to use cnames
