NGINX UI not accessible after change to HTTPS

[jiriteach]

Running a fresh installation of NGINX UI via a Docker container.

services: npm: stdin_open: true tty: true container_name: npm restart: always environment: - TZ=Pacific/Auckland volumes: - /home/administrator/Docker/npm/nginx-core:/etc/nginx - /home/administrator/Docker/npm/nginx-ui:/etc/nginx-ui - /home/administrator/Docker/npm/nginx-www:/var/www - /var/run/docker.sock:/var/run/docker.sock ports: - 9880:80 - 9843:443 image: uozi/nginx-ui:latest

Setup is OK after initially starting the container and accessing 9880 - basically port 80.
Upload my cert and thats OK and valid.

Set NGINX UI to use HTTP under preferences.

Not the WebUI will no longer load.
I am seeing this in the Docker logs -

2025/09/12 06:12:32 http: TLS handshake error from 127.0.0.1:59020: EOF

Strange as the certificates are valid.
Any ideas whats can be causing this? Thanks
