After applying Windows, Edge and Defender security baselines for my customer, on existing computers the behavior of their internal server application changed. Now they all get this warning before going in, but still can get there and the site works. I already disabled some certification checking, but still can't get of this warning. Any direct hint there what to change?

    Hi,

    Cert_Auth_Invalid it seems like your machine doesn't trust the root cert in your chain. Check that the root certificate for your chain is in your trust store and valid, all the chain should be valid and not expired. If you are sure everything is fine with Certs, you can lower the security settings on the PC of the browser also check the reg keys you can download and set the ignore flags for certs but test this on One PC to start with.

    Hope this helps.

    Hi,

    Thank you for your question and reaching out. My name is Louie and I’d be more than happy to help you with your query.

    I understand that you're having issues accessing sites. We can actually perform a Network Reset on it. This process will restore all the default settings of your network connections, may it be wired or wireless or hotspot. By doing this, we're making sure that the connection between the computer and the internet are refreshed and see if the issue can be fixed.

    If you're in Windows 10, click Start menu or search bar, type "Network reset" and open it. From there, you'll see a "Reset now" button, please click on it. Restart the device.

    If you're in Windows 11, go to Settings then Network and Internet then Advanced network settings then Network reset. Restart the device.

    We found a missing certificate chain from setup, so I applied new cert distribution.
