Unable to add UCP node as a replica: etcd misconfigured

(Adyanthaya17) #1


Why is there a fluctuation when it comes to replicating the UCP nodes to the main UCP node? These are the logs below.

Hi adyanthaya17,

What hosts are you running on? (VMs or physical? OS?). Also are you running behind a firewall/blocking certain ports?

I’m able to create the replications, i hadn’t enabled the virtualization iin the machine.

Thank you.
