Rest-server - 404 not found (Docker/FreeBSD)

Hi everyone,
I’ve been trying to set up an instance of the rest-server on a FreeBSD NAS and on an OpenSUSE server via Docker.

On both instances, I managed to set the server up (the only modification I did is adding the --no-auth parameter as I am just testing for now), but on both instances I get a 404 error (this is when running restic init):

Fatal: create repository at rest:http://[IP]:[PORT]/[PATH] failed: Fatal: server response unexpected: 404 Not Found (404)

I am seeing this error both when mapping to an empty /data directory, or to a directory with pre-existing files.

I’ve read the docs and have yet to figure out what I am doing wrong - any help would be greatly appreciated.

Thank you!
