Splunk Cloud Platform

splunk-edge not listening on port 9997

I recently installed a Splunk Edge Processor and i noticed it's not listening on port 9997.  I can see it as a node on the Splunk Cloud Platform but I can't send on-prem data from my universal forwarders to it because it's not listening to port 9997.

 

When I check the ports that it's currently listening to, here are the results:
ss -tunlp

As you can see, 9997 is not in there.  I confirmed the shared settings for this node to make sure that it's expected to receive data on that port:

 

Splunk forwarders

The Edge Processor settings for receiving data from universal or heavy forwarders.

9997
Maximum channels
The number of channels that all Edge Processors can use to receive data from Splunk forwarders.

Any clues as to why this is happening?

Hello @FPERVIL  looks like there its not listening on 9997, may be in issue during the start up of EP. Did you already deploy a pipeline?

Have you tried to check 
edge.log to verify if there are specific errors.?

Yes...this is my 1st deployment of this node.  I installed the software on a linux VM and at a minimum I would think it would be listening and waiting for data via port 9997.  It's definitely connecting to the cloud on that port. 

I don't see anything in the edge.log file that would indicate why it's not listening on that port.  I do see the following but not sure what it may be referring to:

"message":"current settings have previously caused failures. aborting update","type":"provided","status":"failed"},{"time":"2024-10-21T16:16:37.959Z","settings_id":"3080980952365928851","type":"telemetry","status":"running"}]}}
