We are trying to deploy Help (prhelp.war) with Pega 7.4 on Tomcat 8.5.31 / PostgreSQL 9.6 on Linux (RHEL). Browser shows says This page can't be displayed, please check the web site is correct. Initially I thought this is coming from some security settings at this client internal environment, however other war files (prweb.war and prsysmgmt.war) were deployed without any issues so I am wondering if this is a product issue. Should I create an SR for this? Known issue?
Anyways I resolved this issue by just copying prhelp.war under $TOMCAT_HOME/webapps from file system directly. In Tomcat autodeploy is by default enabled, and that means I did not even have to restart Tomcat but it in a second decompressed the file and completed deployment by itself.
