....Cause
According to the following line, Crowd reports that it's not able to resolve the address for the host host.url.com:
1
Caused by: java.net.UnknownHostException: host.url.comResolution
From the machine running Crowd, ensure that the domain name can be resolve via nslookup (or similar). You may need to change the DNS servers used by the Crowd machine, or add an entry to your hosts file to ensure correct resolution.
You can also change the crowd.properties file to a different host name (if the host name is incorrect) with the following steps:
Open
<crowd-home>directoryOpen
crowd.propertiesfile with any text editor and edit the host name
The host name must be the host name of the Crowd server
