*.nelreports.net is a Microsoft domain. Several certificates used on the subdomains of this domain expired last week.

There is no security impact or end-user-impact of the certificate expiration -- Basically, the browser will be unable to submit Network Error Logging reports until the certificate is corrected. Network Error Logging is a HTML5 feature to allow site owners to discover network connectivity problems. https://developer.mozilla.org/en-US/docs/Web/HTTP/Network\_Error\_Logging

Your security software is just announcing "Hey, this certificate is bad", a fact that the browser already was determining on its own, and to which it responds by not connecting to the server in question. The security software provides a redundant warning -- the browser will not use connections with expired or invalid certificates.

The subdomain names are random strings of characters with no particular meaning.

The relevant team has been notified about the certificate expiration and will correct the issue.

    The warning is due to an expired certificate. So ultimately it's up to Microsoft to renew the certificate. If the warnings from Bitdefender and Kaspersky are too frequent, temporarily exclude deff.nelreports.net

    Hola, Kayece,
    una asesora independiente y una usuaria como tú. Estaré encantado de atenderte hoy.

    Para comprender mejor su inquietud, ¿puedo preguntar qué error o alertas de actividad web o URL maliciosa o sospechosa? Es mucho mejor si pudieras enviar la captura de pantalla del error o las alertas.

    Mi antivirus me genera este reporte y no sé si es bueno o malo, todos mis programas son originales, no uso piratería.
