[ABORT][SOLVE][CADDY] Reverse proxy page blanche / Reverse proxy blank page

[Drakonash]

Bonjour,

Je rencontre quelque problème avec la configuration de CADDY en tant que reverse proxy.
j'ai un domaine interne, qui n'est pas géré par nous : "test.local"

Tout les éléments du sous-domaine pointe vers note passerelle opnsense, nous voulions dont effectuer des redirections vers les différents server qui sont derrière la passerelle opnsense (par exemple serveur JENKINS, GITLAB, etc). Nous avons donc configuré CADDY ainsi :

Caddyfile:

Est-ce quelqu'un pourrait m'aiguiller et/ou m'aider ? D'avance merci.
Hello,

I'm having some trouble configuring CADDY as a reverse proxy.
I have an internal domain, which is not managed by us: “test.local”.

All the elements of the sub-domain point to our opnsense gateway, so we wanted to redirect to the different servers behind the opnsense gateway (e.g. JENKINS server, GITLAB, etc). This is how we configured CADDY:

Caddyfile:

But i found something strange, when WAN it's down and change CADDY conf, save take 1 seconde but when WAN it's UP save take  more than 30 secondes

Before someone say, i have fixed error with "Custom Configuration Files".
Rename "/usr/local/etc/caddy/caddy.d/01-tuned.conf" into "/usr/local/etc/caddy/caddy.d/01-tuned.global"

And it seem solve the problem with long save time (think because now Caddy not try to solve OCSP)

Bon nous avons décider d'utiliser un autre plugin (Nginx) avec lesquels nous avons réussi à fonctionner comme
attendue.


So we decided to use another plugin (Nginx) which worked as expected.
