What is the issue you’re encountering

I configured Origin CA c ertificates and added them to a .pem file and a .key file on my origin server (NGINX). I point my NGINX conf to them. Unfortunately, when I leave TLS verify turned on, it gives me a 502 error, when leaving it off, it works as intended.

What steps have you taken to resolve the issue?

Turned off TLS verify

This is my config:

server {
    # Listen on port 443 for HTTPS
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name subdomain.batzbak.top;

    # SSL certificates
    ssl_certificate /etc/ssl/certs/batzbak.top.pem;    # Path to your SSL certificate
    ssl_certificate_key /etc/ssl/private/batzbak.top.key; # Path to your SSL private key

    # Proxy settings to forward traffic to local server (e.g., localhost:5000)
    location / {
        proxy_pass http://ip:port;  
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # WebSocket support (if applicable)
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

# Redirect HTTP traffic to HTTPS
server {
    listen 80;
    server_name *.batzbak.top batzbak.top;

    location / {
        return 301 https://$host$request_uri;  # Redirect all HTTP requests to HTTPS
    }
}```
