bzib and deff.nelreports Phishing Protection
(msedge.exe attempted to establish a connection relying on an expired certificate to deff.nelreports.net. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk.)
This problem hasn't gone away, I've also reported to MS.
A fix has been posted on an earlier post, but I ran Winsecurity.diagcab and it reset phishing protection which had been turned off.
My system is running Windows 11 Pro insider preview evaluation 23585.1001 with VPN, bitlocker & bitdefender
