Environment

Release : 22.2

Cause

Name-resolution issue:

On the PC/Portal host, the Ping does not resolve this hostname:

# ping pc_host

Also, the curl syntax fails:

# curl http://pc_host:8281/EventManager/DataSourceWS.asmx?wsdl

Resolution

Fixed the name-resolution issue by adding the short hostname in the /etc/hosts file.
