Yes, it works on my system. omv 4 + nc13 but i have installed 12.0.x and updated to nc13.

Can you please post your nginx config?

I don't know why there is HTTP redirect loop.

Can you share your vhost config ?

My current config is based on the official Nextcloud sample. Basically I only added security settings and the omv-generated $socket.

Code

upstream php-handler {
    server 127.0.0.1:9000;
    #server unix:/var/run/php5-fpm.sock;
}


server {
    listen 80;
    listen [::]:80;
    server_name my.domain.com;
    # enforce https
    return 301 https://$server_name$request_uri;
}


server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name my.domain.com;


    ssl_certificate /etc/ssl/certs/cert.crt;
    ssl_certificate_key /etc/ssl/priv.key;

We not suppose to turn on the PHP default config.

@FixXx,

Apparently, I have the same issue when I ran the test on sslabs.com.

Another issue is : This server supports weak Diffie-Hellman (DH) key exchange parameters.

Solution:

Note: This process may takes 15 to 30 mins depends on your service specs.

1. Go to and run:
Code
cd /etc/ssl/certs
openssl dhparam -out dhparam.pem 4096
2. Add this line at the beginning of the vhost config:

ssl_dhparam /etc/ssl/certs/dhparam.pem;

I have no problem with the ssllabs score. I got A+, 100 in every category... thx to this excellent documentation.

My main problem is the reported /login loop. I've used the vanilla nextcloud13 config to sort the problem out. The config works after i made the common changes (server, cert, root, $socket) but the redirect loop persists.

Do you - does anyone - have an idea what the reason could be? Is there someone out there with omv4+nc13 installation and without redirect loop reported by ssllabs?

Ensure your Nginx and PHP are running.
Some users have the same issue like yours.
It could be incorrect socket.

You can try to turn off the PHP default configure option, and do the followings:

Replace fastcgi_pass $socket with fastcgi_pass /run/php/php7.0-fpm.sock;

service nginx restart
service php7.0-fpm restart

I had luck with this change and could install nextcloud 13 on omv4 successfully. Thanks for your hard work and investigation!
Now I have checked my server against the ssllabs servertest and got - i think - a https-redirection-loop.

Do you experience the same with your config or have an idea what the cause could be?

My nginx config:

Code

server {
listen 443 ssl;
listen [::]:443 ssl;
ssl_certificate     /etc/ssl/certs/cert.crt;
ssl_certificate_key /etc/ssl/private.key;
set $root_path "/path/to/root";
root $root_path;
index index.php;
set $socket "unix:/var/run/fpm-b4f19467-563b-4681-b8e4-582ee046726b.sock";
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass $socket;
}
