Get this opaque error when trying to register Portal and the GIS Server with the Web Adaptor on Red Hat Linux. All are 10.5.1; two versions of Web Adaptor with Tomcat (unique names). Any other diagnostics I can try?
Did you have a previous version on the machine? If so, did you undeploy and de-deploy the WAR file?
No previous version; this is a fresh install of all three components. Initially also I tried to only do the single Web Adaptor deployment... that failed with Portal so I tested with GIS Server.
What is the WAR file?
