i added a new host to the authorized hosts list and after that i am unable to access the manager from all of my network, even from the server it is installed on it
please help me to resolve this issue
you should try accessing the console from the system you configured on the GUI Access tab.
Otherwise, you can log into the mysql database and run this command to disable access control:
update iv_emsproperties set value='false' where name='iv.access.control.enabled';
Then restart the NSM service.
