Collabora Office on Debian Plesk, vhosts config

I got my Nextcloud running on https:

Now I want to install collabora Office, i know the offical

I got collabora installed via docker
I createt a save subdomain over Plesk and the embedded LetsEncrypt https
I know that I have to use https: in the docker run command
I run all a2enmod commands as noticed in the offical TO DO.

The only question I have I am very, very unsure how to configure the VirtualHost properly.

  1. Where ist this thing (virtualHost) stored? I have acces over Plesk and SSH to my Debian 8X and Iā€™m running several subdomains as vhosts. Where should I look and store?

  2. How to configure the file, when I already used LetsEncrpt with Plesk for my
    Becaus it says: "# SSL configuration, you may want to take the easy route instead and use Lets Encrypt!"
    What to fill in know?


I tried following nginx code. I can only change it directly in Plesk (see Plesk docu)
FYI: I hide my domain with

<VirtualHost *:443>			


		# SSL configuration, you may want to take the easy route instead and use Lets Encrypt!
		SSLEngine on
		 ssl_certificate             /opt/psa/var/certificates/cert-cc7e0I
    ssl_certificate_key         /opt/psa/var/certificates/cert-cc7e0I
    ssl_client_certificate      /opt/psa/var/certificates/cert-VvFQmK


		# Encoded slashes need to be allowed
		AllowEncodedSlashes NoDecode

		# Container uses a unique non-signed certificate
		SSLProxyEngine On
		SSLProxyVerify None
		SSLProxyCheckPeerCN Off
		SSLProxyCheckPeerName Off

		# keep the host
		ProxyPreserveHost On

		# static html, js, images, etc. served from loolwsd
		# loleaflet is the client part of LibreOffice Online
		ProxyPass           /loleaflet retry=0
		ProxyPassReverse    /loleaflet

		# WOPI discovery URL
		ProxyPass           /hosting/discovery retry=0
		ProxyPassReverse    /hosting/discovery

		# Main websocket
		ProxyPassMatch "/lool/(.*)/ws$" wss://$1/ws nocanon

		# Admin Console websocket
		ProxyPass   /lool/adminws wss://
		# Download as, Fullscreen presentation and Image upload operations
		ProxyPass           /lool
		ProxyPassReverse    /lool

This will not be acceptet, Plesk comes back with:
Invalid nginx configuration: nginx: [emerg] unexpected end of file, expecting ";" or "}" in /var/www/vhosts/system/ nginx: configuration file /etc/nginx/nginx.conf test failed

Any ideas?
