I'm working on a backend API service in Golang using Mux Router. On my localhost the endpoints work perfectly fine, but deployed, only the endpoints that are 1 level deep in the subrouter will work. /api/v1 is my subrouter path prefix.

Here are some examples:

/api/v1/species GET works perfectly fine deployed via github, hosted on railway and on my localhost

/api/v1/habitat GET works fine too on both environments

/api/v1/enclosure GET, POST, PUT, DELETE all work fine in both environments

/api/v1/user/login works fine on localhost but does not work on the railway hosted environment (404)

/api/v1/admin/species works on localhost but not on railway (404)

/api/v1/admin/habitat works on localhost but not on railway (404)

I've looked thru the logs and everything but cant seem to find any sort of clues as to whats happening. Not getting any descriptive errors or anything, just the 404 response. Let me know if you need more context to help. Below are the versions im using in my codebase.

Golang v1.23.4

Gorilla Mux v1.8.1

repo is https://github.com/whitallee/animal-family-backend if you want to take a look at the source

Thanks for any help at all!
