MFS blocking allowed sites

Question

Allowed you tube kids on MFS. This works fine if kid account is logged in but if computer is shut down and then turned back on MFS blocks access to youtube kids and displays 'youll need to ask to use this site' for a very long google.com address. When this is allowed it the also links to a site which is not allowed. These not allowed sites seem to be because the kids youtube is not logged in. The only work around i have so far is to shut off all mfs in my childs account and then go into his computer and log him in via my parent access. This then allows him to click on youtubekids.com and get in. As soon as the computer is shut off it logs him out and we are back to square 1 and a very frustrated child who doesnt understand why it is blocking him. And a frustrated me! Is there any way around this ultra irritating system? We havent found one yet but am guessing this ay also happen with other sites with logins?

Answer 1

This is a common issue with Microsoft Family Safety (MFS) and sites that require persistent login, like YouTube Kids. The problem happens because:

• When the PC restarts, the child account logs out of YouTube Kids.
• MFS then sees requests to Google domains (for login/auth) and blocks them unless explicitly allowed.
• Even if you allow one long Google URL, the login flow often redirects to other Google services that aren’t on the allowed list.

Why It Happens

MFS doesn’t automatically whitelist all related domains for a service. YouTube Kids uses multiple Google endpoints (accounts.google.com, gstatic.com, youtube.com, etc.), so if the child isn’t logged in, the login process triggers blocks.

Possible Fixes

1. Add All Required Domains to Allowed List
   • Allow these domains in MFS:
   • youtubekids.com
   • youtube.com
   • accounts.google.com
   • google.com
   • gstatic.com
   • ytimg.com
   • This covers login and media loading.
2. Enable “Always Allowed” for YouTube Kids App
   • If using the Windows app or browser shortcut, mark it as “Always Allowed” in MFS.
   • For browsers, ensure the app/site is pinned and allowed.
3. Use App Instead of Browser
   • If possible, install the YouTube Kids app from Microsoft Store or use the mobile app on a tablet. Apps often bypass some web filtering issues.
