How to increase timeout for a request beyond 10 seconds

[darkweak]

You’re running the cache in debug mode (log_level debug directive).
About the hit TTL issue, I can’t explain that and I don’t know how to reproduce because on the CI tests I ensure the computed TTL is the right one.

Maybe you could tell me more in detail what you meant how I should do it?

Use the log directive with no block/options inside of your site, which makes the logger write to the default logger.

In your global options you configured the global logger (by not providing a name) which writes to an access.log file, which is named incorrectly because the default logger doesn’t write access logs (unless you use the log directive inside of a site – it configures runtime logs, i.e. everything else).

Look for http.log.access logs, which are access logs. They should be written for all requests, even ones which the cache module intercepts.

I bamboozled myself.
I did run caddy via caddy run --config /etc/caddy/Caddyfile and then pressed ctrl+c so I could faster test different configs but I did not notice that if caddy did not cleanly shutdown the next instance would happily start even though there was already one caddy instance running.
First I did expect that ctrl+c would actually kill it and second that it would instead of starting error out with port is already in use both is not the case.
That explains also why I got different ttls and requests would not end up in the log, they were answered by a instance with a much older config.
I’m very sorry and thank you everybody for your help.

Since I did ask multiple questions and the thread title is not really suiting all this anymore I will post here my complete webserver configs I run currently if somebodys finds this via google.
Please be aware this is configured to my personal taste and may doesn’t make sense in a future (also I run this on a pretty slow OpenWRT device, so I’m not even sure if this would work on a Debian or CentOS), so it is more a start point for a personal config and less suited to use as copy and paste.

my nginx is build with headers more and quic
add to your nginx.conf

Thank you francislavoie and darkweak for all your help

I’m not sure why you’re using nginx at all in this setup, you could do all that with just Caddy, with way less config, and with TLS automation built in.
