Hello :slight_smile:

I have a Proxmox server with a NGINX server. As VPS I have a Nextcloud. I can login via IP.

My Proxmox is avaible via a Domain. I want the Nginx as reverse Proxy to my cloud and other services. I have this code in proxmox.conf

upstream proxmox {
    server proxmox.domain.com;
    
}
 
server {
    listen 80 default_server;
    rewrite ^(.*) https://$host$1 permanent;
}
 
server {
    listen 443;
    server_name proxmox.domain.com;
    ssl on;
    ssl_certificate /etc/ca-certificates/crt.crt;
    ssl_certificate_key /etc/ca-certificates/key.key;
    proxy_redirect off;
    location / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade"; 
        proxy_pass https://localhost:8006;
	proxy_buffering off;
	client_max_body_size 0;
	proxy_connect_timeout  3600s;
        proxy_read_timeout  3600s;
        proxy_send_timeout  3600s;
        send_timeout  3600s;
    }
}

upstream php {
    server nextcloud.domain.com;
}
server {

    listen 443;
    server_name nextcloud.domain.com;
    ssl on;
    ssl_certificate /etc/ca-certificates/crt.crt;
    ssl_certificate_key /etc/ca-certificates/key.key;
    proxy_redirect off;
    location / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade"; 
        proxy_pass https://192.168.178.139:443;
	proxy_buffering off;
	client_max_body_size 0;
	proxy_connect_timeout  3600s;
        proxy_read_timeout  3600s;
        proxy_send_timeout  3600s;
        send_timeout  3600s;
    }
}

Here are the Ports of the Apache

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

Listen 80

<IfModule ssl_module>
	Listen 443
</IfModule>

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


NameVirtualHost 127.0.0.1:8080
Listen 127.0.0.1:8080

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Here ist the nextcloud.conf of the Apache:

<VirtualHost *:80>
 DocumentRoot "/var/www/html/nextcloud"
 ServerName nextcloud.domain.com

Redirect permanent / https://nextcloud.domain.com
Alias nextcloud.domain.com /var/www/html/nextcloud
 ErrorLog ${APACHE_LOG_DIR}/error.log
 CustomLog ${APACHE_LOG_DIR}/access.log combined

<Directory /var/www/nextcloud/>
 Options +FollowSymlinks
 AllowOverride All

 <IfModule mod_dav.c>
 Dav off
 </IfModule>

 SetEnv HOME /var/www/htm/nextcloud
 SetEnv HTTP_HOME /var/www/html/nextcloud
 Satisfy Any

</Directory>

</VirtualHost>

I have change the Ports to 80/443 and I get everytime Bad Gateway 502

Here is the error Log of the Nginx server. The errorlog if Apache is empty.

2021/04/10 14:41:47 [error] 2684#2684: *197 connect() failed (111: Connection refused) while connecting to upstream, client: 91.184.168.251, server: nextcloud.domain.com, request: "GET / HTTP/1.1", upstream: "https://192.168.178.139:443/", host: "nextcloud.domain.com"

What I is wrong with this configuration? I tried a couple of options out of the Internet, but nothing works :confused:

I think the Apache refused it for security reason. But I don’t know where I can config this, to get the Server run behind the reverse Proxy.

Can anybody help me? :slight_smile:
