I have setup funkwhale (via docker compose) behind nginx reverse proxy (regular service) and it is working fine. However, I only managed to serve it via the root path, e.g. mydomain.com. With other services I was able to make them available as mydomain.com/myservice. I attempted to do the same for funkwhale mydomain.com/funkwhale. Other services usually needed to know the base path, but for funkwhale I only found FUNKWHALE_HOSTNAME (mydomain.com), not the base path itself. Any hints?
