Auto installer stuck at "Starting node 2 (ndbmtd)" with 29% (no replies)

Trying to install Cluster 7.6.6 across (3) RHEL7 servers (1 mgmt/SQL and 2 data nodes). I used "web application" and "low" as the choices.

I started the cluster, but the progress bar has been at 29% for over 3 hours. Do I sit and wait? Or where do I look to get more details?

Here is the output of ndb_mgm:
ndb_mgm> SHOW
Connected to Management Server at: localhost:1186

Thank you,
