It appears some disabled "Policy Manager access" so now we are unable to login using the policy manager.
Is there anyway to re-enable this via command line or external of using policy manager?

Release : 9.4

Component : API GATEWAY

This is stored in the ssg table 

Review the following instructions,

# mysql ssg

mysql> select name, port, endpoints from connector where port = '8443';

On my system gives me,

| Default HTTPS (8443) | 8443 | MESSAGE_INPUT,ADMIN_REMOTE_ESM,ADMIN_REMOTE_SSM,ADMIN_APPLET,OTHER_SERVLETS |

Assumabily your missing the ADMIN_REMOTE_SSM

You can just do the select then add this value to an update.

update connector set endpoints = 'MESSAGE_INPUT,ADMIN_REMOTE_ESM,ADMIN_REMOTE_SSM,ADMIN_APPLET,OTHER_SERVLETS' where port = '8443';

This should do the trick or if its 9443 change the port above to 9443 etc..
