If you previously used the frevvo.forms.server.external.url property to set your forms server external URL, this property has been deprecated. Instead, configure a Tomcat proxy in the HTTP connector (port 8082) of the <frevvo-home>\tomcat\conf\server.xml file. See the External URLs Documentation for instructions.

The frevvo.internal.baseurl property no longer exists in v10+. It is replaced by frevvo.internal.port. Any setting in frevvo.internal.baseurl will be ignored by frevvo.

The connector with port 8081 was newly added to server.xml in v10+. Please ensure this port is available for  to use. As indicated in the server.xml, changing the frevvo internal connector 8081 settings in the server.xml file can cause unexpected changes, and is not advised.
