Execute the ff: Script
delete from ossys_parameter where name = 'ClientApplicationToken';
delete from ossys_parameter where name = 'privateKeyValidation';
delete from ossys_Parameter where name = 'OutSystems.HubEdition.MobileLogin_AuthenticationHMACKey';
delete from ossys_Parameter where name = 'OutSystems.HubEdition.MobileLogin_AuthenticationEncryptKey';
delete from ossys_dbconnection;
After executing the script restart the APP Server. Then reconfigure the Configuration Tool.
