The value of conf.suite.SERVER_AND_PORT in custom.properties located in <APPIAN_HOME>/ear/suite.ear/conf does not exactly match the URL used to access Appian.
Modify the value of conf.suite.SERVER_AND_PORT so that it matches exactly the URL used to access Appian.
Note: When using a web server with port 80 or 443, the suffixes :80 and :443 should not be included.
