Issue Problem with the Varnish + Nginx proxy configuration on plesk

[negurah]

Hello

I followed the official tuto for the Varnish via Docker configuration on plesk. https://www.plesk.com/blog/product-t...cker-container

i have a VPS Ubuntu with plesk and many domains.

I followed all steps :

• I created a domain test.monserveur.com
• I use the Docker image million12/varnish
• On the Docker container setting, the mapping redirect the 80 port to the 32780
• On plesk for the hosting parameters, the option “SSL/TLS support” and “Permanent SEO-safe 301 redirect from HTTP to HTTPS” are deactivated
• I deactived also the security mod for this domain
• On the proxy rules of the docker container (/etc/varnish/default.vcl), i put fo the .host test.monserveur.com and .port 7080
• On the function sub vcl_deliver, i put :

if (obj.hits > 0) {
set resp.http.X-Cache = "HIT";
} else {
set resp.http.X-Cache = "MISS";
}

I still have a 503 page with a MISS on the header for the page on test.monserveur.com

I can't understand where is the problem. I tried to put on the .host the serveur IP and with a link to another domain of the server. I think it's a problem with a setting but i don't know where.

Thanks in advance
