invalid certificate warning for doh.xfinity.com keep popping up
h/t user_cb87dc (previous identical issue - why can't we just re-open)?
"As already this topic explains,
Xfinity Overwolf Expired Certificate
Xfinity's doh server's certificate is expired, and this warning is shown in many Xfinity customer's PC with Kaspersky security software (both business and individual).
also in my PC, it's related with browsers (Edge, Google Chrome) and Google Drive.
Xfinity, just please update your doh.xfinity.com certificate. I don't want to take care of this on all my customers' PCs. (my job is computer support)"
This issue has returned - Kaspersky is continually bombarding me with warnings about it.

Do what this person says, and FIX IT! We shouldn't have to call you. Ridiculous! I'm trying to work and it's driving me insane.

Yeah, I'm not sitting on the phone anymore either.
There's a problem, we're customers, you're an employee, escalate to a tech that can fix it. This is ridiculous.

I am getting the same error message repeatedly since October 7!!!!!!!!!!!!!!!!!!!!!!!!! Really. It looks like I may need to switch to a different internet provider.

I see that this isn't a new issue according to the above link. Doesn't look like the situation was resolved 2 years ago and I'm willing to bet it won't get solved this time. Has anyone contacted Kaspersky about this?

I called the 888 #. The agent couldnt help me. Got transferred to another agent who reset my xfinity router. That didnt work either. He told me that the security team would work on it and the issue would be resolved in two hours. That hasnt happened.
Maybe its time for everybody with this Kapersky issue to post it across their social media platforms. If it spreads on social media Xfinity/Comcast might decide that fixing the problem is better than negative publicity.

I have a hunch what is going on here, since this goes away if you turn off the Kaspersky email antivirus (which many people won't want to do). I expect Kaspersky is doing some version of a DMARC DNS check. The Xfinity DNS server is misconfigured so is glitching with annoying popups.
There might be simple fixes in terms of changing the DNS defaults which could be tried if you want to hack into the configuration. Better would be Xfinity patched their DNS.

Same issue. I keep getting this message daily. Called the number above and the lady told me my internet doesn't have doh or overwolf and would escalate it to the dept. above/level 2.
