Found the reason
Checked the on-line documentation of Communigate and found this:

When I try to log in, I get the "access from your network is denied" error.
You have selected the Reject all Logins from Non-Client Addresses option on the Protection page. Now you can connect to the Server only from the addresses listed in the Client IP Addresses field (on the same page).
If the Client IP Addresses field was left empty, you still can connect to the Server if you launch your browser on the Server computer itself, and connect locally, using the http://127.0.0.1:8010 URL.
If you have not entered anything into the Client IP Addresses field, or if you cannot connect from the IP Addresses listed in that field, and you cannot connect to the server locally, using the http://127.0.0.1:8010 URL, then:
stop the CommuniGate Pro Server;
open the {base}/Settings/IPAddresses.settings file and change the ClientOnly option from YES to NO, and save the updated file.
start the CommuniGate Pro Server again.
Will change this tonight and check tomorrow.
