If you changed the port, make sure that you have updated spring security port-mapping (it should already use the configuration service and these properties via spring EL in order to do this if you use the latest version of hybrids), and for local development - URL resolution site ( website.<x>.http(s) , media.<x>.http(s) ) and the URL of the CMS website URL that displays regular expressions (ImpEx or hMC). I also think this property is for jvdbc.
You can change them in config/local.properties , platform/project.properties or the custom extension project.properties . The local.properties file has the highest priority (if the property is defined in several places), then the user extension project.properties and, finally, on the project.properties platform.
