"The supervisor is offline" warning message is shown in the TIBCO Spotfire Administration Web UI

Sometimes you might see a warning messages in Web UI > Nodes & Services > Notifications saying:
 

The supervisor is offline. ID: 037bcc00-5fac-4cc4-aeaf-60d545def799{code}

This usually happens after upgrade of the environment or migration to the machine 1. Open command prompt in '<Spotfire Server installation>tss\X.X.X\tomcat\spotfire-bin' (if using TIBCO Spotfire Server 7.14 or older, use '<Spotfire Server installation>tss\X.X.X\tomcat\bin' instead) and run command 

config list-nodes

2. Note down ID's of the nodes that have status of "Online: no". For example

Remote nodes:
Node ID                               Server Name                  Site     Has Valid Certificate  Is Online  Last Seen
------------------------------------  ---------------------------  -------  ---------------------  ---------  -----------------------
f2f44685-83e5-4cf1-a144-25a6ccd569e3  your.server1.com  Default  yes                    yes        2018-02-27 09:45:59 CET


Server nodes:
Node ID                               Server Name      Site     Has Valid Certificate  Is Online  Last Seen
------------------------------------  ---------------  -------  ---------------------  ---------  -----------------------
3448d90b-25e9-45a2-9db5-76af5cbd712e  your.node1.com  Default  yes                    yes        2018-02-27 09:46:43 CET
c2f42685-83e5-4cf1-a144-25a84hjf34dv  your.node2.com  Default  yes                    no         2018-01-16 14:13:54 CET

in this case offline node ID is c2f42685-83e5-4cf1-a144-25a84hjf34dv

3. Run  "config delete-node --id=<node-id>" where node-id is ID of the offline node. For example:

config delete-node --id=c2f42685-83e5-4cf1-a144-25a84hjf34dv

After a few moments, the warning messages will disappear
