Problème de configuration de Nginx Varnish

0

J'essaie d'installer le vernis avec SSL à partir de ce lien: https://www.linode.com/docs/websites/varnish/use-varnish-and-nginx-to-serve-wordpress-over-ssl-and-http -on-debian-8 /

J'ai tout fait comme après, mais j'ai maintenant l'erreur "Je manque juste un petit truc, mais je ne sais pas où.

Ici / etc / nginx / sites-available / default:

    server {
   listen  443 ssl;

voici / etc / default / varnish (je viens de changer ces lignes):

Merci pour ton aide

Qu'espérez-vous réaliser avec "return (synth (850," "))"; " ?

En fait, je ne suis pas sûr mais je pense que cela fait partie de la redirection HTTP vers HTTPS

Si je ne me trompe pas, le 850 devrait être un code de retour HTTP valide, dans votre cas peut-être un 301 ou 302, pour que le navigateur suive la redirection.
