Problem: 

Unable to add a node to a ProfileUnity 6.8.5 cluster, the error presented is "Remote node https://<pu_consolename.com:8000/' did not communicate back."

This is most likely do to certificate failure on one of the nodes please check for valid certificate on ALL nodes:

Open this link to all consoles from any browser on the network:

https://FQDN_console_1_name.com:443/api/getlicensingcertificate

On the pop-up login box, login with the prou_services account and password. 

The correct output should look like this:

(The line should start with: {"success":true,.....})

If there is a problem the result will look like this:

(The line would start with: [success":false,.....})

 

Resolution:

On the console which shows "false" (fails to generate certificate) please remove (and re-install new) "Liquidware ProfileUnity License Server Certificate" by following steps below:

  1. Open mmc.exe on the server
  2. File>Add Snapin>Certificate "Open" >Local Computer
  3. Delete ALL "Liquidware ProfileUnity License" Certificates from:
    1. Personal/Certificates
    2. Trusted Root Certification Authorities/Certificates
    3. Example 1: mceclip0.png
    4. Example 2: mceclip1.png
    5. Go to services and restart "Liquidware Labs ProfileUnity Licensing Service" (This will generate a new Liquidware ProfileUnity License" Certificate)
    6. Try again to test the certificate with this page: https://FQDN_console_1_name.com:443/api/getlicensingcertificate 
    7. If the result is "success":true Restart ProfileUnity Server wait 5 minutes and try to add node again to the cluster.
