Hi
I have installed passbolt on a machine with nginx without ssl force ,but i have a another nginx self-hosted in my network it act as public proxy server so i wanna open my passbolt in public with ssl and when i configure nginx i got the result 200 in access log file but the webpage is blank and nothing to show, while i can open passbolt via private ip address, the reason why i am doing this because i just have a 1 public ip address , so could anyone help me 
Here is the access logs:
"GET /auth/login?redirect=%2F HTTP/2.0" 200 1107 "
And Here is my front public proxy config:
upstream pass1 {
server 192.168.10.112:80;
}
server {
listen 80;
server_name pass.example.com;
# Redirect HTTP to HTTPS
return 301 https://$host$request_uri;
}
server {
listen 443 ssl http2;
server_name pass.example.com;
