Webauth.comcast.net.443 uses an invalid security certificate

Asked By 0 points N/A Posted on -


Hi there,

I use SeaMonkey to browse websites and it works fine. However, recently an error message continues to appear. It seems that this message does not appear in other browsers e.g. Internet Explorer, Opera or Firefox. The web pages display normally though the error message is very annoying.

I have contacted ISP Comcast to find any solutions and they do not help and simply ask me to use another browser like IE. Does anyone know that if the configurations or settings are incorrect? And what should I do to tackle the error? Thanks in advance.

Hi there Joseph E Ahart,

The most common reason for certificate issuses is wrongly set date and (or) time on your computer, so that should be the first thing you should check.

You can easily adjust your date and time by clicking on the clock in the right corner of your taskbar and then choosing the 'Change date and time settings..' option.

Another thing you can do is to click on the 'View certificate' button in your error. That will open a new dialog box and allow you to get a new certificate that will work.

Best regards,
Drake Vivian
