Hello OpenBSD ports team,

I am using the latest pre-compiled package of anubis (anubis-1.17.0) on 
my machine in order to safeguard my gitea instance, that I reverse proxy 
using caddy, against scraping. The gitea instance is running on a linux 
machine in the same network and is accessible at http://192.168.1.2:3000 
over my LAN. When trying to place anubis between caddy and the gitea 
instance using the following configurations, the starting anubis page 
loads, but it gets stuck at "Loading..." and doesn't actually proceed to 
give the hash challenge to the client or let them access the service. It 
is also odd that the robots.txt page is served by anubis. The anubis 
configuration that I am using is:

export BIND=:8923
export DIFFICULTY=4
export METRICS_BIND=:9095
export SERVE_ROBOTS_TXT=1
export TARGET=http://192.168.1.2:3000

and the part of the caddy configuration that is important to this issue is:

domain.name {

   reverse_proxy localhost:8923 {
                header_up X-Real-Ip {remote_host}
                header_up X-Http-Version {http.request.proto}
        }
}

I also want to mention that using basically the same configuration for 
anubis and caddy (changing 192.168.2.1:3000 to localhost:3000 and 
localhost:8923 to 192.168.1.2:8923) and running the anubis instance on 
the linux host, I was able to get anubis and caddy working. Anubis 
version was the same for both systems.


Here is also the OpenBSD version from sysctl -n kern.version:
OpenBSD 7.7 (GENERIC.MP) #625: Sun Apr 13 08:30:20 MDT 2025
deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP


I don't think that I have anything else to add. If you'd like for me to 
provide anything else, even provide a live domain to see the issue in 
action please let me know.  If I made a mistake and there is a 
maintainer that I should have sent this email to instead of the ports 
team, I apologize.


Thanks for your time
