In our QS setup we were trying to configure system as Multi-Node environment (Central + 1 Rim)
Due to internal network limitations, I have to convert "Rim Node 1" to "Central Node 2".
I've uninstalled QS from Rim Node 1 and have installed it back with "Central Node" option selected.
The installation went well and all Qlik services are up and running, but I am unable to launch QMC or Hub on the system. The message: "This site can’t be reached".
The version installed: QS 3.1.1
The issue was caused by Duplicate certificates not removed during un-installation.
From Logs: "Error: Duplicate or invalid root certificates are not allowed".
Resolution: QS uninstalled (with selecting option to removed certificates).
System is up and running after re-installation.
