What is bzib.nelreports.net and deff.nelreports.net in relation to Microsoft Edge?

I am a Microsoft Edge user and I have recently noticed that my browser is attempting to connect to bzib.nelreports.net and deff.nelreports.net. My security software, Bitdefender, has flagged these connection attempts due to an expired certificate.

I would like to understand why these connections are being made and whether this is expected behavior for Microsoft Edge. If it is, could you please provide some context as to what bzib.nelreports.net and deff.nelreports.net is used for? If it’s not expected behavior, could anyone advise on the steps I should take to address this issue?

Note: This issue was fixed on 15 Nov 2023 by updating the site's certificates.

Explanation:

Several certificates used on subdomains of this domain expired last week. Certificate expiration has no impact on security or the end user. Basically, the browser will not be able to submit network error logging reports until the certificate is fixed. Network error logging is an HTML5 feature that helps site owners discover network connectivity issues.

Your security software simply announces "Hey, this certificate is bad", a fact that the browser already determined for itself and responds to by not connecting to the server in question.

Security software provides a redundant warning; the browser will not use connections with expired or invalid certificates.

Subdomain names are random strings of characters with no particular meaning.

The appropriate team has been informed of the certificate expiration and corrected the issue.

    Same with me. Bit defender just started bombarding me with notification about 6 hours ago and saying:
    "msedge.exe attempted to establish a connection relying on an expired certificate to bzib.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to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk."

    And

    "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to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk."

    Hi, I am Dave, I will help you with this.

    1

    Open Edge, then click the 3 dots at the top right and open Edge Settings

    On the left, click 'Start, Home and New Tabs'.

    Are those settings set correctly to either 'New Tab Page', or your preferred start page, and is there any sign of those two 'nelreports.net' addresses in there?

    2

    When Edge redirects to those two web addresses, when does that happen?
