I have installed docker on Ubuntu-21.04 and I'm trying to run apache/nifi on it. I am using this command: docker run --name nifi -dp 8443:8443 apache/nifi. From the logs all seems fine:

2022-03-24 15:39:27,726 INFO [main] org.apache.nifi.web.server.JettyServer NiFi has started. The UI is available at the following URLs:
2022-03-24 15:39:27,726 INFO [main] org.apache.nifi.web.server.JettyServer https://a8917820086b:8443/nifi
The entire logs are here
But if i go at localhost:8443 I see this: on firefox and on chrome. I don't know why I can't access to the UI of Nifi. I have done all of this exactly on windows 10 and it works. Someone can help me? Thanks in advance.
You need to go to https://localhost:8443 not http://localhost:8443. By default NiFi is now secured with TLS, but 8443 is not the standard HTTPS port, thus it does not automatically redirect you to HTTPS if you only enter localhost
