Running 2 WLS instance on a same server

Hi,

I have a WLS 12.1.3 running on an instance.

I was working to spin up WLS 12.2.1.3 on the same machine on a different port.

After the 12.2 installation i confirmed that ./startWeblogic.sh and ./startNodeManager runs fine.

but when I try to start the ManagedServer in WLS console, i get an error

**For server ManagedServer, the Node Manager associated with machine Machine-1 is not reachable.
Message icon - Warning All of the servers selected are currently in a state which is incompatible with this operation or are not associated with a running Node Manager or you are not authorized to perform the action requested. No action will be performed.

In WLS console, under environment>machine>machine_1>monitoring I see an error even tho Keystore/SSL tab is configured correctly (configured same as 12.1.3 which has no problem starting managed server)

**Status: | Inactive | Current status of this Node Manager.More Info…
Problem description: | javax.net.ssl.SSLHandshakeException | Exception encountered while communicating with this node manager.More Info…
Version: | (not available)

To add a little more context, nodemanager.properties is pointing to port 5557 same as nodemanager in WLS console.

when i upgraded one of our training environment from 12.1.3. to 12.2.1.3, it had no issue. Is it not feasible to run parallel WLS on a same machine?

Any feedback will be appreciated and please let me know if more information is needed.

Thank you,
