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.

    I have the same issue. Searching for answers on the internet produces various opinions from 'its malware and a danger' to 'it's perfectly okay as its Microsoft'. I am perfectly happy for BitDefender to block all background connection attempts including bzib.nelreports.net and deff.nelreports.net. Either Bitdefender will eventually add them to a safe list, Microsoft will get new certificates, or they will continue to get blocked if genuinely harmful. Its once less thing for me to worry about.

    SOLUCIONADO

    TIENE QUE IR A LA AP DE EXPLORADOR Y RESTAURARLA

    IR DONDE ESTAN LAS APLICACIONES Y RESTAURAR EL EXPLORADOR DE MICROSOFT

    Y LISTO DESARARECEN LAS NOTICIAS DE BITDEFENDER Y NO APARECE NINGUNA NOTIFICACION MAS

    Hi,

    Assuming this translation is correct...

    "SOLVED

    YOU HAVE TO GO TO THE EXPLORER APP AND RESTORE IT

    GO WHERE THE APPS ARE AND RESTORE MICROSOFT EXPLORER

    AND THAT'S IT, THE BITDEFENDER NEWS DISAPPEARS AND NO MORE NOTIFICATION APPEARS"

    ...what is meant by "restore" Explorer?

    Do you mean "restart"?

    ========================

    In general, the BD notifications are incessant; hope Windows updates those certificates soon!

    So can we do anything about this? Or do we have to wait for it to be updated.

    I also tried uninstalling the NEWS app, and it did not stop it from happening, even after a restart of my PC
