Hi,

I have also seen this error several times. In my experience, it is
almost always caused by a misconfiguration of Nginx.

On my equipment, there is an exception to that rule when Nginx serves
outside connections as a reverse proxy to the local network, i.e.
something like: [1]

(body (list
  "proxy_pass http://lechner-desktop.us-core.com:3011;"
  "proxy_set_header Host $host;"
  "proxy_set_header X-Real-IP $remote_addr;"
  "proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;"))

but that's somewhat exotic. It triggers a "host not found" in the logs.

My particular failure may have to do with the service ordering in
Shepherd, although I have not been able to fix it. For example, the
default prerequisites for Nginx do not even include 'networking. [2]
Either way, Nginx is configured to respawn, so my bug is probably
elsewhere.

Closing this issue.

Kind regards
Felix

Hello Guix!

I am using certbot-service-type which also brings in nginx service. Upon 
`guix system reconfigure`, I get the following:

guix system: warning: exception caught while executing 'start' on 
service 'nginx':
Throw to key `%exception' with args `("#<&invoke-error program: 
\"/gnu/store/g6nhdp7i1sr51anq86hd6adrsm5ha857-nginx-1.21.0/sbin/nginx\"

\"/var/run/nginx\") exit-status: 1 term-signal: #f stop-signal: #f>")'.

Regards,
RG.
