Symptoms
Provider wants to add domain registered elsewhere in CCP such as domain.zone.tld but was prompted with error message:
Domain name should contain only one "dot" symbol
Cause
The issue caused by configuration setting in POA > System > Settings > System Properties for 'Allow using of several dots in domain name' is disabled.
Resolution
In order to add domain with more than 1 dot symbol, provider need to enable the setting 'Allow using of several dots in domain name' in System Properties.
