Unable to get a simple example working about souin HOT 6 CLOSED

I do not actively maintain the standalone server because of the multiple constraints to built a reverse proxy. I recommend to use Souin as middleware in caddy or traefik reverse proxy. However I will investigate on that panic but in my first opinion, the Souin standalone server is designed to run in front of another reverse proxy (Apache, nginx, caddy, Træfik, ...). You cannot proxy directly to google but you should have something like
Incoming traffic -> Souin -> traefik -> service and your Souin configuration should be

default_cache:
    ttl: 30s
reverse_proxy: http://traefik

from souin.

What's the difference in terms of having a "local (maybe virtual) network" upstream (traefik) vs. a remote upstream (google)?

Anyhow, if the standalone server is not maintained maybe it should be made more clear in the readme? By reading here: https://github.com/darkweak/souin#souin-out-of-the-box and seeing otherwise just use https://yourdomain.com I assume differently.

Træfik is a reverse proxy, Souin is not. yourdomain.com is the domain to use to contact the reverse proxy and transfer the request to it.

I've added traefik as you suggested. I'm no expert in the service so I followed and adapted the basic example found on the traefik docs.

Panic is still there.

version: "3.7"

services:
  proxy:
    image: darkweak/souin:v1.6.28
    ports: 
      - 80:80
      - 443:443
    volumes:

      - "traefik.http.routers.whoami.entrypoints=web"

log_level: DEBUG

  port: # Ports to expose Souin
    web: 80

  ttl: 10s # Default TTL

(EDIT: I've also tried downgrading Souin, that's why I'm using 1.6.28 here)

I'll explore using souin as a middleware.

That's a bug then 😅

Well I opened a PR that handle HTTP proxy errors. In your case, you have to put a real proxy between your souin instance and the service you want to proxy the request (caddy is easier to configure for that). If you target http://google.com or http://www.google.com it will work because there are no TLS verifications and it's not on the roadmap to support that.

I can come back later with an example using caddy if you need it.
