There are many profiles used in EBS. But below are the few profiles which are used to setting up the correct URL in EBS.
Mostly values for these profiles are populated from context files when we run autoconfig.
 
But in some cases when the EBS instance is cloned/refreshed or DMZ setup is performed then we need to make sure that these profiles are properly set at site level and server level(in case of DMZ setup).
 
The hostname and web port should be defined properly.
