Products

Issue/Introduction

We do have a Spectrum Oneclick instance 10.4.3. onclick webapp is not working, 

Opening a blank page.

Environment

Release : 10.4

Component : Spectrum Applications

Cause

Connection configured for HTTPS, showing blank when trying with HTTP

Resolution

Check %SPECROOT%/webtomcat/conf/server.xml 

Check the connector entry configured for http / https

if it is configured for https then we need to launch OneClick Home Page with https then click on WebApp

<Connector port="9443" enableLookups="true" disableUploadTimeout="true" tcpNoDelay="true" acceptCount="100" scheme="https" secure="true" SSLEnabled="true" clientAuth="false" sslProtocol="TLS" ciphers="TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_256_GCM_SHA384, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA256, TLS_DHE_RSA_WITH_AES_256_CBC_SHA256" keystoreFile="E:/CA/spectrum/custom/keystore/keystore.jks" keystorePass="test123" sslEnabledProtocols="TLSv1.2"/>

Now you should be able to launch webapp
