Issue

In Atlassian Administration, the left sidebar path Apps → Sites fails to load sites. Instead of listing sites, it shows grey loading skeleton bars for an extended period and eventually displays "Error loading sites".

Accessing the same organization's sites via the direct Sites URL works correctly, so the issue appears specific to the sidebar "Apps → Sites" navigation and/or its data-loading path.

• Org overview URL:
  https://admin.atlassian.com/o/<ORGID>overview

• Direct Sites URL (works):
  https://admin.atlassian.com/o/<ORG ID>/sites

Steps to Reproduce

1. Log in to Atlassian Administration for the organization:
   https://admin.atlassian.com/o/<ORG ID>/overview
2. In the left sidebar, click Apps to expand the submenu.
3. Click on Sites under Apps.

Expected Result

• The Apps → Sites view in the sidebar should:
  • Load and display the list of all sites for the organization.
  • Allow navigation to individual site details from that list.
  • Handle organizations with a large number of sites (including backup/restore test sites) without timing out or failing.

Actual Result

• On clicking Apps → Sites:
  • Initially, only grey skeleton loading bars are shown in the sidebar content area.
  • After some time:
    • In Chrome: the page eventually shows "Error loading sites".
    • In Edge: the grey loading bars persist and never resolve (no list displayed, no explicit error beyond the loading UI).

• No sites are shown in this "Apps → Sites" view, even though sites clearly exist for the org.

However:

• Navigating directly to:
  https://admin.atlassian.com/o/<ORGID>/sites
  correctly loads and displays the sites.

• This confirms:
  • The org and its sites are valid.
  • The problem seems specific to the sidebar Apps → Sites UI path and/or its backend/query.

Known Workaround

1. Bypass the sidebar path and access sites directly via:
   https://admin.atlassian.com/o/<ORG ID>sites
2. From there, I can:
   1. View the full list of sites.
   2. Access and manage each site normally.
