Hi ramin,
if you want to allow access to Knowage from the outside you have to properly configure the server so that it is possible to reach the application.
For user configuration, I remind you that Knowage 7.4 provides integration with LDAP, Azure Sign-In and Google Sign-In
I also inform you that we do not respond by email. If you need professional support, please contact us at knowage@eng.it
Greetings
Alberto
