Any additional Information

Hi guys. Can somebody point me to the right direction?
I’m new with rocketchat, but willing to learn.

  1. I followed the manual installation on the rocketchat website
  2. This is the content of my port 80 virtualhost
    <VirtualHost *:80>
    DocumentRoot /var/www/html/chat.mydomain/
    ServerName chat.mydomain
    ServerAlias www.chat.mydomain

<Directory /var/www/html/chat.mydomain/>

RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

  1. This is the content of my port 443 virtualhost

  2. This is the content of my rocketchat service

  3. This is the error I get from the page

  1. This is what I get in the log files

My questions.
1.There is a comment to include Environment=HTTP_FORWARDED_COUNT=1 in the rocketchat file for a proxy. I did that. Is that what the instructions want?
2. In my virtualhost port 443 I have the Let’s Encrypt certificates. Notice that I do not have any intermediate one, but according to the logs this does not appear to be a problem. Or it is?
3. The errors are toward the end of the logs and seems related to the proxy_fcgi and proxy_http.
How should I go about solving them?

Thank you guys.
