Lets Encrypt Plugin und Proxy

**ciscllc** · Oct 31st 2017

Hi!

Ich habe das Lets Encrypt Plugin (Version 3.3.0) und schaffe es nicht, domains (subdomains) mit proxy mit einem Zertifikat zu versorgen.
Der Proxy ist für Proxmox und geht daher auf https://subdomain.domain2.de:8006

i-mscp 1.5.1
php 5.6
debian 8.9

Hi

Wie in den Logs steht:
Lets Encrypt kann http://subdomain.domain.de/.we…ziK56keKAKAzXiF0nT4ZNaLU8
nicht erreichen.

Wie hast du den Proxy denn genau eingerichtet?

Über i-MSCP direkt.

Also: Domains --> Bearbeiten --> URL Weiterleitung --> >Weiterleiten zu URL https://subdomain.domain2.de:8006/ --> Typ PROXY, "Host erhalten" aktiviert.

Aber auch über die /etc/apache2/imscp/subdomain.domain.de.conf

Code

ProxyRequests Off ProxyPreserveHost On SSLProxyEngine On SSLProxyVerify none SSLProxyCheckPeerCN off SSLProxyCheckPeerName off SSLProxyCheckPeerExpire off RequestHeader add X-Forwarded-Ssl on RequestHeader set X-Forwarded-Proto "http" RequestHeader set X-Forwarded-Port 80 <Location /> ProxyPass https://subdomain.domain2.de:8006/ retry=0 ProxyPassReverse https://subdomain.domain2.de:8006/ # Websocket ProxyPass wss://subdomain.domain2.de:8006/ retry=0 ProxyPassReverse wss://subdomain.domain2.de:8006/ </Location>

meine sites-available conf sieht so aus:

Code

<VirtualHost 555.123.123.123:80>

Sollte es mit der Standardeinstellung nicht gehen?

Hi

Habe es auf meinem Server selber ausprobiert, bei mir kann ich problemlos ein Zertifikat auf eine weitergeleitete Subdomain ausstellen.
Der Proxy selber Funktionier aber problemlos?
