When pressing Upgrade button in Agents, nothing happens.


In nolio_dm_all.log there is following error :

Release Automation 6.x


a ES node is linked to itself as supernode.
Following Query shows some rows with same value for server_id and super_node_id
select * from connected_super_nodes


1- Update the properties of "Execution Servers" and remove the links to itself.
Example :
In below screenshot one ES is linked to itself. We should remove the link by clicking on the red cross
2- If some NES is not reachable, it is not possible to remove the link using GUI.
But it could be deleted using a SQL Query
Execute following SQL Query :
DELETE FROM connected_super_nodes WHERE server_id=super_node_id
to remove the links NES to itself
3- Restart Nolio service on NAC
