Apache Nifi is not starting: Management Server Address System Property

[#1]

I am new to nifi trying to install it but when I run command nifi.cmd start I get this:

JAVA_HOME=C:\Program Files\Java\jdk-21
NIFI_HOME=C:\nifi-2.7.2-bin\nifi-2.7.2

but it doesn't write that "nifi has started" when I checked the log file it has the following:

nar\extensions\nifi-server-nar-2.7.2.nar-unpacked\NAR-INF\bundled-dependencies\nifi-ui-2.7.2.war] Context Path [/nifi]

I already added the "org.apache.nifi.management.server.address=127.0.0.1:9990" in properties file but that didn't work too what I should do ?

management.server.address -- defines HTTP URL on which NiFi listens for management requests.
Doc Ref : https://nifi.apache.org/nifi-docs/administration-guide.html

Please try setting below property as part of " bootstrap.conf " and then start the Nifi service.
java.arg.mng12=-Dorg.apache.nifi.management.server.address=127.0.0.1:<port-number>

Please check if the port-number <for example: 9990> is not defined and replace the same in the property
