Failed to bind DNS

[#1]

I am trying to run Nifi in a docker container on an EC2 instance.  However, whenever my container starts I am seeing the following error. 

2022-06-14 02:23:51,093 WARN [main] org.apache.nifi.web.server.JettyServer Failed to start web server... shutting down.

I have added the following in the nifi.properties file. 

nifi.web.http.host=

nifi.web.http.port=

nifi.web.http.network.interface.default=

#############################################

nifi.web.https.host=ec2-xx-xx-xx-xx.us-east-2.compute.amazonaws.com

So  java.net.BindException: Cannot assign requested address is an error occurred while attempting to bind a socket to provided hostname and port. Typically, the port is in use, or the requested hostname could not be assigned, Are you sure port is free and no issues with the hostname you are using ?
