Why is there Master UI issue after upgraded to v9.1.0.2?

Loves-to-Learn Everything


We were running v9.0.5 and I upgraded the master to v9.1.0.2.  This is on CentOS 7.  The upgrade ran successfully, rebooted, and splunk started with all ports opened:

Checking prerequisites...
Checking http port [8000]: open
Checking mgmt port [8089]: open
Checking appserver port []: open
Checking kvstore port [8191]: open

These are running for splunk status:

splunkd is running (PID: 4730).
splunk helpers are running (PIDs: 4784 4828).

Inside the instance, I can ping localhost.  But when I ping localhost 8000; it hung for a long time.

Also, from my indexer instance; I can ping the master ip but not with port 8000 and 8089.

I checked security groups and such.  Ports are allowed.  Nothing changed.  The UI was running before I started the upgrade.

Anyone ran into this issue with the upgrade?
