Xfinity Overwolf Expired Certificate

@Ensign_Garak That is odd! Can you access https://comca.st/3A4CTuS then search DOCSIS Certification?

Thank you for your response.  Yes @BruceW , that is correct.  This is something that needs to be fixed on the Comcast side, as someone needs to renew a certificate that has expired for "doh.xfinity.com", @XfinityHeather .

I tried to call Customer Service about this last night, and the representative transferred me to a Technical Support line that didn't recognize the button presses that I was making on my smartphone.  So, I was unable to proceed with this call.

How can this get reported to the right area within Xfinity/Comcast to get this certificate renewed?  Thank you very much.

Hello, @Ensign_Garak, great question! So the best recommendation that I can provide to this as to getting that certificate updated/renewed or at the very least getting the process started would be to speak with our Customer Security Assurance team. You can reach them by calling 1-800-Xfinity (1-800-934-6489) at your earliest convenience during the hours 8:00 AM - 12:00 AM ET/Seven days a week. :) 

Thank you for the suggestion, @XfinityNicki .  Unfortunately, after 30 minutes on the phone with various representatives, and most recently, with a representative from Customer Security Assurance, I am being transferred back to Technical Support with the thought that this is a problem on my end, not on Xfinity's end.  We'll see where they decide to send me.  Thank you. 

UPDATE: Unfortunately, upon getting transferred to Technical Support, the call got disconnected from the Xfinity end.  I hope that someone calls back....

@Ensign_Garak

Thank you for letting us know and for all the time you are spending working on this with us. Please keep us posted and let us know if you need anything else.

Well @XfinityDevinC , what I need is for someone at Xfinity to understand what the problem is, and not disconnect my call without calling back.  Now I have to go through the whole process all over again.

If you folks replying to me are Xfinity employees, can't someone just bring this problem to the correct resource at Xfinity without my having to jump through all these hoops?  Frankly, I am getting quite frustrated with all of this.

Also, I have to admit that I am a bit surprised that I am unable to find anyone who is able to tell me what the Xfinity app "Overwolf" does, and why it is running on my computer.  I would really like to know what it's doing.

@0lena​ Thank you for posting your comment.  I have read of other folks experiencing this problem, so it is nice to have a comment like that directly in this post.  Unfortunately, the problem has not yet been fixed according to my system.

Here's just a sample of what I am dealing with on my side:

@Ensign_Garak Advanced Security is enabled on the Gateway, which may stop a device connected to the home network from visiting a potentially dangerous site. Utilize the xFi app and review their threat history in the Notification Center to see if the website they are trying to access is listed there. We will continue to assist you in in a PM from here. Thank you. 

As you can see from the stream of complaints about the expired certificate issue on the Xfinity side, the issue to still prevalent.  I have been trying everything on my side to no avail.  Please check your certification.  I get the following message from my security software:

"chrome.exe attempted to establish a connection relying on an unmatching security certificate to xfinity.comcast.net. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one."

Calling is useless.  If you did an update at xfinity, you may check your toggles.  Something is wrong at your end.
