App Client connection check uses your saved URL (v4.106.1)
On the Configuration settings page, the connection check now tests the production URL saved for your workspace. While you edit the URL, the badge shows Reachable when your browser can load it, and the full check runs once you save. Workspaces that load the App Client from a separate internal address see Save to check until the change is saved.
The check is now available to workspace admins only.
