Bitdefender, Certificate revoked

Hi,

Have seen some posts about this already. Seems like this issue is happening every 9 months or so.

First there is the messages on NextDNS site: 

Error while checking the current status.

Please talk to us if this problem persists after refreshing the page.

At the same time Bitdefender is throwing continuous Critical Notifications in online threat Prevention:

Feature:

Online Threat Prevention

chrome.exe attempted to establish a connection relying on a revoked certificate to s2r5wyobin-xxxxxxx.test.nextdns.io. We blocked the connection to keep your data safe since revoked certificates are usually fraudulently obtained or used

Is there any more information you require?

Any ideas how to solve it?
