Rapid Development Kit (RDK) on Linux doesn't work properly when access with hostname or IP address to RDK server.
For example,

Installation Guide explains not to use localhost or FQDN to access RDK server.
However, it is possible that hostname doesn't work like http://<hostname>:<port>/rdk. Because installer automatically may set FQDN to <tomcat>/webapps/rdk/resouces/config.properties file instead of hostname.
Please check <tomcat>/webapps/rdk/resouces/config.properties file on RDK server. The configuration may depend on network configuration.
If you see FQDN in config.properties, you should attempt FQDN to access RDK as well. http://<FQDN>:<port>/rdk
