Splunk containerized. I receive: "Error while sending public key to search peer" when i try to add a search peer

[massimo_ciceri]

hi everybody.

I have three Splunk instances in three docker containers on the same subnet . I have mapped port 8089 on port 8099 on each container. No firewalls between them. I checked the route from/to all containers (via port 8099) and there are no blocks and no issues...

But when i try to add on of the containers splunk as a search peer in a distributed search deployment, i always receive the error "Error while sending public key to search peer"

Any suggestion about this?

Thank to everybody in advance.
