This article explains the procedure on how to resolve if the Address page keeps loading with Blue Circle for a single user.

In an attempt to make changes to the address objects or create a filter, the page ends up loading with Blue Circle for a single user. Due to this, the User will not be able to make any changes. This rotating Blue Circle will not get resolved after refreshing the Browser, clearing the browser's cache and cookies, or even restarting the JBOSS service or restarting the Junos Space server.

• Login to the Junos Space using Super User
• Delete the Issue User from "Role-Based Access Control > User Accounts"
• If it's a Local User, create the User again from the User Accounts page and then try to login to the Junos Space from a Browser New Tab using the newly created User.
• If it’s a Remote User, don’t create the User manually as it will get created automatically when you try to login to the Junos Space from the Browser New Tab.
• Go to the Addresses page and the page should be accessible.
