I follow the steps.

  1. Downloaded MiNiFi c2 server in Windows where my NiFi is running.

  2. Created a template using NiFi UI with name given examplename iot-minifi-raspberry-agent.v1

  3. Canged MiNiFi c2 property port - 8080 (U was also getting port 10080 is already in use)

  4. Changed minifi-c2-context.xml property

    <constructor-arg> <value>http://localhost:9090/nifi/</value> </constructor-arg> in this url my nifi is working,so this only changed

  5. My MiNiFi is running in different Windows machine. There I changed bootstrap property like below

    ---------------------------------------*****--------------
# Hostname on which to pull configurations from
nifi.minifi.notifier.ingestors.pull.http.hostname=localhost

# Port on which to pull configurations from
nifi.minifi.notifier.ingestors.pull.http.port=8080

# Path to pull configurations from
minifi.notifier.ingestors.pull.http.path=/c2/config

# Query string to pull configurations with
nifi.minifi.notifier.ingestors.pull.http.query=class=iot-minifi-raspberry-agent ----// name of my template ?? should i use version also like .v1

# Period on which to pull configurations from, defaults to 5 minutes if commented out nifi.minifi.notifier.ingestors.pull.http.period.ms=60000

-----------------------------------*****-------------------

  6. Now all changes are done I check whether my changes are done correctly by hitting below URL

    http://localhost:8080/c2/config?class=iot-minifi-raspberry-agent.v1&version=1

    I can see yml is showing but that is already present in MiNiFi

    c2 -->files folder

What am I doing wrong or where is my understanding incorrect?

Any help would be really appreciated. Thanks in advance

You say that your minifi is running on diffeent machine, So your bootstrap configuration is wrong. Your host name to pull configurations from must be on which your minifi-c2 server is running and not local. This should work.
