Account users with admin permissions or higher use this article to resolve an issue where the dashboard spins indefinitely after selecting Save when adding a domain to an Allow List or Block List.

Use an incognito or private browsing window

1. Open the dashboard in an incognito/private window
2. Retry adding the domain — browser extensions or system settings may block expected page actions

Check for network errors

1. Reproduce the issue while recording a HAR (HTTP Archive) file
2. Look for a net::ERR_HTTP2_PROTOCOL_ERROR in the logs; this often points to bad cache or interfering extensions
3. Clear the browser cache and disable active extensions
4. Retry the action

If the issue persists, capture a fresh HAR file and submit a Support request for further review.
