Kafka cannot connect to stream node - 8.4 Personal Edition
After a fresh install with no errors, I noticed that pzStandardProcessor was not running. Log errors show that Kafka cannot connect to stream node:
com.pega.fnx.stream.spi.StreamServiceException: Unable to connect to the stream provider.
caused by: org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment.
The stream node in question is running normally under the proper address.
Kafka's controller log further confirms the issue:
[2022-10-28 10:16:58,589] WARN [RequestSendThread controllerId=1001] Controller 1001's connection to broker Proprietary information hidden:9092 (id: 1001 rack: null) was unsuccessful (kafka.controller.RequestSendThread)
java.io.IOException: Connection to Proprietary information hidden:9092 (id: 1001 rack: null) failed.
I assume the problem is with the port. Port forwarding can be problematic as I am on a corporate network. What can I try to make it work?

I am running PE 8.4 on a vm and this seems to be working fine, pzStandardProcessor is running. I can confirm that port 9092 needs to be open for localhost access.
One guess is that it might be antivirus running on your system that is blocking this. Maybe you can try to exclude C:\PRPCPersonalEdition\jre1.8.0_121\bin\java.exe from the local antivirus protection policy settings.
Also check the local Windows Firewall and open port 9092 if possible, or completely exclude the java.exe from the Windows firewall policy
