Issue/Introduction

The dcdebug URL http://DA:8581/dcdebug/ is getting redirected to: https://DA:8382/sso/sign-in.jsp?SsoProductCode and ends in error.

However http://DA:8581/rest/ is working.

Attempting to access http://DA:8581/dcdebug/ with a REST client results in the following error:

 

java.net.UnknownHostException: DA
     at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
     at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:929)
     at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1324)
      ...

Environment

DX NetOps CAPM Release : 22.2 or later

Cause

Hostname is used instead of the Fully Qualified Domain Name (FQDN) in DA name resolution with DA in Portal -> Data Sources being registered with a hostname.

Resolution

Change DA hostname to FQDN in Portal Data Sources.

Additional Information

In Sso (CAPC), the parameters:Web Service Host & Web Site Host are the same. 
CAPC and DA names are resolvable.
