Troublshooting guix-publish make-systemd-constructor

Hi Guix,

I have the following in my operating system services:

(service guix-publish-service-type
          (guix-publish-configuration
           (port 9090)
           (host "localhost")))


However, trying to connect to port 9090 from localhost hangs.

`ss -tunlp | grep 9090` shows shepherd listening however:

tcp   LISTEN 0      128                          127.0.0.1:9090       0.0.0.0:*    users:(("shepherd",pid=1,fd=23))

I could use some tips on what's wrong with guix-publish, and more 
generally how to troubleshoot systemd services.

Thanks!
Jack

I use this [1] and also have (service avahi-service-type) [2] but do not
know how to troubleshoot. It just worked.

Kind regards

Thanks! I found the problem, and it didn't have anything to do with the 
service. I did have an older system generation where it worked, and I 
determined that the difference was switching iptables v. nftables for a 
firewall, and an oversight in the iptables config that was dropping 
packets on the loopback interface. Oops! It is nice that Guix makes it 
easy to switch back and forth like that. Thanks again for your reply.

Best,
Jack
