No slave scheduler found

Hi.

We're trying to configure a RIM node to our existing central node. We did all the steps on the how to and defined the central node as a manager scheduler and the RIM node as worker.

When we execute a task we get the error: "No slave scheduler found" and this message on the log: "Slave-node XXXX.net is not alive and cannot run task XXXX".

We followed the steps detailed on: https://community.qlik.com/t5/Knowledge/Qlik-Sense-Enterprise-on-Windows-reloads-fail-with-no-node-found/ta-p/1712654 as it seems to be the same case but when executing the powershell on the RIM node we get the following error:

Any advise on how to get rid of these problems?

Thanks

Hi,

Can you add at the beginning of these scripts the following code in order to enforce the use of TLS1.2

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Best regards

Added and same error is being reported:

Also this is only a test but the real problem is the tasks failing on RIM node execution

Thanks for checking.

Have you deployed the sense certificates correctly on the Rim node? Are the ports opened and are you able to telnet from one machine to the other on these ports?

Best regards

Hi,

Yes, the certificate is deployed when configure the rim node though the asistant right? Accesing the configuration URL on the RIM node and putting there the password generated. All the ports are opened (in this case if I'm not wrong the important ones are 5050 and 5051)

I'm able to telnet both ports.
