Hi Jeff, try logging into ArcGIS Server Manager and under Services > System, try restarting the CachingTools service and the PublishingTools service. If that doesn't fix it, try logging into the ArcGIS Server Admin endpoint, and go to Services > System, and open each of these 4 services and restart them all: CachingTools, CachingToolsEx, PublishingTools, PublishingToolsEx. Then try publishing again.
