I have created a HDF cluster in azure using CloudBreak. I am facing the below issue while trying to connect to Nifi UI.
I see that Nifi process is running on VM and netstat shows that process is listen on port 9091 but still I am unable to access the Nifi UI. I would request someone to help resolve the issue.
To avoid creating many firewall rules I suggest you restrict the access to your IP by getting your IP using https://www.iplocation.net/find-ip-address
The in the azure firewall configuration allow all ports but restricted to ONLY your IP
That ensures no one else can access the Nifi except from your laptop but if not you will need a site2Site VPN setup and create an admin subnet that has access to nifi and put all nifi users in that subnet.
