Nifi container running but not accessible via UI – Docker

I am very new to docker and Nifi so please understand if my question doesn’t sound refined.

When I downloaded Nifi from official apache nifi website and fired it up, it was accessible via http://localhost:8443/nifi

But when I created a docker container using the following command

docker run -itd -p 8433:8080 --name nifi apache/nifi

it runs without a problem but it’s not accessible via web UI

When I used

docker logs d7 | grep "JettyServer"

2022-07-07 23:17:13,334 INFO [main] org.apache.nifi.web.server.JettyServer NiFi has started NiFi has started. The UI is available at the following URLs:
2022-07-07 23:17:13,334 INFO [main] org.apache.nifi.web.server.JettyServer https://d723418f https://d723418f16d5:8443/nifi

above message was shown, which to my understanding it means that Nifi is running.

I have tried

-localhost:8433

-host IP:8433

-bridge network IP:8433

but none of those work.
Is this possibly because of the update on version 1.14.0 since it accesses UI via https rather than http and requires ID and password now ?
Or am I just missing something very simple?

Thank you all for your help in advance.

    I changed the port setting to 8443:8443 and added /nifi to the URL and it started working

    By default nifi listening only 8443 port (and using HTTPS connection)

    If you want to connect using unsecure HTTP, you need to set HTTP port:

    docker run -itd -p 8443:8080 -e NIFI_WEB_HTTP_PORT=8080 --name nifi apache/nifi

    In this case HTTPS connection will be disabled and you will be able to connect with http://localhost:8443/nifi instead of secured HTTPS

    ＊ It is not possible to activate both 8080 (HTTP) and 8443 (HTTPS) connection at same time. You have to edit container entrypoint
    script (/opt/nifi/scripts/start.sh) to activate both connections
