Trying to synchronize the application list results in a timeout and following log entry can be found:
2017-08-15 13:52:22.971 [http-nio-8080-exec-3] ERROR c.c.r.c.c.RestControllerAdvice - Connection timeout on call to http://10.130.97.21:8080/cdd-ra-plugin/api/application-source/applications with args [Ar
gument{name='apiUrl', value='http://10.130.97.21:8080/cdd-ra-plugin/api/application-source/applications'}]
com.ca.rp.exceptions.rest.PluginException: Connection timeout on call to http://10.130.97.21:8080/cdd-ra-plugin/api/application-source/applications
timeout settings in settings.properties are set too small
Locate the settings.properties file within the CDD home folder (default /root/.cdd in Linux, C:\.CDD in Windows).
Check the existence of following lines:
cdd.plugins.client.http.connection.timeout=600000
cdd.rest_template.connect.timeout=600000
cdd.plugins.client.http.read.timeout=600000
cdd.rest_template.read.timeout=600000
If they exist, change them to:
cdd.plugins.client.http.connection.timeout=1800000
cdd.rest_template.connect.timeout=1800000
cdd.plugins.client.http.read.timeout=1800000
cdd.rest_template.read.timeout=1800000
If they do not exist, add those lines.
Afterwards restart Tomcat.
