Thanks, @[deleted]
I did a fresh install with all recommendation.

Install Confluence in Production with Docker everything is was working fine.

First thing I did was change proxy in server.xml.
Updated base URL in Confluence https://confluence.domain.com/
The problem which I troubleshoot is from NGINX configuration.

Postgres 9.6 is on different docker.
Confluence is on different docker.

But both are on the same server. so I used network so that they can talk. But problem is when updating Nginx with suggested configuration it is not working problem is
nginx: [emerg] upstream "confluence.domain.com" may not have port 8091 in /etc/nginx/conf.d/default.conf:123

updated Nginx configuration
# confluence.domain.com 8091
upstream confluence.domain.com {
## Can be connect with "docker_intranet" network
# confluence
server 172.19.0.8:8090;
}
server {
server_name confluence.domain.com;
listen confluence.domain.com:80 ;
access_log /var/log/nginx/access.log vhost;
return 301 https://$host$request_uri;
}
server {
server_name confluence.domain.com;
listen 443 default ssl;
access_log /var/log/nginx/access.log vhost;

Hi Gaurav,

I understand you are getting XSRF errors when you access Confluence over https through your NGINX proxy. Please see this article for conditions that cause XSRF errors: Cross Site Request Forgery (CSRF) protection changes in Atlassian REST

For an example of how to set up the NGINX proxy to work with Confluence, please refer to Running Confluence behind NGINX with SSL.

I look forward to hearing how it goes.

Thanks,

Ann

PS - I think there is a typo on your PostgreSQL version, as 9.6 is commonly used and 6.9 is quite old.
