After following the existing KB article (Article ID: 232536, Spectrum webapp not working after upgrade) we are still unable to start up the WebApp.
I get the following message:; "Request processing failed. Please refer the tomcat log for more details. ...Not able to reach OneClick Webapp. "
Looking at the tomcat catalina.out file I see the following entry:
"javax.net.ssl.SSLException: Unsupported or unrecognized SSL message"
Release : 21.2
Component : Spectrum OneClick
