Key notes
Recently, a lot of users had their antivirus sending notifications about a certificate error fordoh.xfinity.com. Even when accessing the website, they were informed of the certificate issue and that it expired on Friday, September 8, 2023.
In most cases, Kaspersky antivirus flagged the SSL connection and reported the expired certificate. It’s mostly a problem on the server side, but DNS queries and requests, or an incorrect date and time, could also be the culprit.
What is thedoh.xfinity.comcertificate error?
The error indicates that the certificate assigned to the website has expired or is not properly configured. Subsequently, an encrypted connection cannot be established between the server and the application, say Adobe AcroCEF or Overwolf.
