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

Anonymous

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.

I am also getting such notification about "bzib.nelreports.net" and "deff.nelreports.net".

However, I found a solution to stop it, but it is not very helpful for Edge users. It may effective to only those who do not use edge.

Here it is:
1. Settings> Cookies and site permissions> Cookies and data stored> Manage and delete cookies and site data>Allow sites to save and read cookie data (recommended): off
Click/tap on the three dots right of the profile picture of edge. Then go to settings, from left select Cookies and site permissions, from right panel, click/tap Manage and delete cookies and site data (below Cookies and data stored). The turn off the active button of Allow sites to save and read cookie data (recommended).
1. Settings>System and performance>
Startup boost: off

Continue running background extensions and apps when Microsoft Edge is closed: off

Like step 1, from the left select System and performance and from the right turn off Startup boost and then turn off Continue running background extensions and apps when Microsoft Edge is closed.

Click/tap on the three dots (right of the profile picture) and select Close Microsoft Edge from the bottom.

Again, it may cause problems to those service that require Edge running in background and it is not for Edge users, because it will cause sign in issues in edge.
