I want to run Caddy as Reverse Proxy with Varnish 6.6 and Magento 2.4.2

a. System environment:

Ubuntu 20.04 Focal ( Digitalocean droplet )

b. Command:

systemctl start caddy

c. Service/unit/compose file:

}

3. The problem I’m having:

Hi guys,
1- can someone help me to get config file ( Caddyfile or Json ) to run Caddy2 with Varnish >6.0lts and Magento 2.4.2, and use Caddy as Reverse proxy with Aytomatic Https or LetsEncrypt.

PS: my ports config
Apache2 listening = 8080
Apache2 TCP6 listening = 443
Varnish listening = 80
Varnish listening = 8443
Varnish TCP6 listening = 80
Caddy listening = 80

thank you in advance

Please use ``` backticks before and after your configs and logs, on their own lines, to use code formatting. It’s very difficult to read your post without it, because whitespace is not preserved.

Also, please run the command listed in the docs below to view your logs. You’ll notice your logs are truncated with a > at the end of each line when using systemctl status caddy, which hides the important messages.

Hi, its my first time posting here, thank you

This error is saying Caddy failed to start because some other process is already using port 443.

It’s not possible for two different processes to use the same ports. You’ll need to move your Varnish and Apache servers away from using ports 80 and 443, because Caddy needs ports 80 and 443 to solve ACME challenges, to automate certificate issuance for you.

this is my ports.conf apache2

Listen 127.0.0.1:8080

<IfModule ssl_module>
	Listen 443
</IfModule>

<IfModule mod_gnutls.c>
	Listen 443
</IfModule>

i removed Listen 443 from Apache2 and change Varnish to 8880,
now i have error HTTP ERROR 404.

curl -I mysite.com

HTTP/1.1 308 Permanent Redirect
Connection: close
Location: https://mysite.com/
Server: Caddy
Date: Wed, 01 Sep 2021 20:14:31 GMT

That’s not an error. That’s Caddy performing an HTTP->HTTPS redirect. Use the -L flag in curl to follow redirects (i.e. L for the Location header), or just use https://mysite.com as the address.

8

but the website still not accessible in the browser.
ERROR 404

can someone help me to get config file ( Caddyfile or Json ) to run Caddy2 with Varnish >6.0lts and Magento 2.4.2, and use Caddy as Reverse proxy with Aytomatic Https or LetsEncrypt, ON APACHE2
