FusionAuth, Nginx inside Azure Container App

Trying to run FusionAuth inside container app using Nginx as a proxy to provide the required 443 Forwarded-Port header.

When I try to access FusionAuth URl, it just spins before giving stream timeout. Here's my Nginx conf file.

server {
    listen 80;
    server_name myserver.australiaeast.azurecontainerapps.io;

    location / {
        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;
        proxy_set_header    X-Forwarded-Port '443';
        proxy_http_version  1.1;

        proxy_pass https://myserver.australiaeast.azurecontainerapps.io;
    }
}

and here's the Dockerfile

FROM fusionauth/fusionauth-app:latest
COPY ./fusionauth.properties /usr/local/fusionauth/config

FROM docker.io/library/nginx:latest
COPY ./nginx.conf /etc/nginx/conf.d/default.conf

Any help greatly appreciated!
