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.

    Someone might have suggested this already, but the way I fix it is by updating the hosts file to point those two domains to essentially nothing.

    1. Open C:\windows\system32\drivers\etc\hosts in notepad as admin.
    2. Add the following lines at the bottom.

    0.0.0.0 deff.nelreports.net

    0.0.0.0 bzib.nelreports.net

    1. Save
    2. Restart Edge.

    Now each time your browser tries to visit those addresses it'll just end up going off to 0.0.0.0 (basically nowhere) and fail silently.

    I am certainly on the same page as you there. I trust Bitdefender much more in the security field than I do Microsoft. If they were going to let a service go defunct, they should be removing that service, or removing that server. Seems like this issue is going to be a wait and see type of thing, either way, Bitdefender can keep blocking whatever Microsoft is doing, or lack thereof.

    I do find it funny, with the type of push MS makes for people to use their services and applications, that this wouldn't be priority for them.

    I swapped to Edge from Firefox, as it had appeared that Edge was making strides in the right direction. I've enjoyed the browser as well as the built in AI's capabilities. I will be swapping back shortly if Microsoft does not resolve.
