Could not contact master. Check that the master is up, the master_uri=https://xx.xx.xx.xx:8089 and secret are specified correctly.

I am trying to configure index clustering for our environment. Currently, I have 2 Indexers and both peers refuse to join the master, not sure why, but the Master URI and Secret Key seems to be perfect.

Hi,

did you check your firewall?? Traffic on port 8089 should be open.
