Tomcat Startup Freezes at "Appian component Search Server is healthy"

My installation process took a bit of a circuitous route and now there seems to be something missing.  The tomcat server gets to this log point, then just freezes:  

2020-06-25 19:20:16,844 [wait-for-component] INFO  com.appiancorp.common.startup.WaitForStatefulComponents - Appian component Search Server is healthy

no other logs are generated after this point.

anyone have any ideas what to try?  All three servers are like this.

Thanks,

Jeff.
