Bitdefender Blocking Nextdns due to revoked certificate

Bitdefender Message:
Feature:
Online Threat Prevention

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

    No answer for this report?

    I have the same: on my device Bitdefender throwing the same notification and closing access to NextDNS so it is not in use.

    For me, everything was good, then hundreds of notifications from my primary security software. Notifications now average over 500 every few hours at the least, and I've seen it hit 800 +.

    Does anyone think that the Security, and Privacy filters we can turn on in Next DNS dashboard could be causing the issues? Before https://dns.nextdns.io started to be primarily blocked due to a revoked certificate by my primary security software, a bunch of other domains were being blocked. So I turned off some privacy filters, and kept only the Next DNS, and AdGuard ones. Keep in mind, I'm still testing Next DNS, and still on the FREE plan.

    It also seems this issue is an ongoing, intermittent one, maybe due to how Next DNS works in the backend? Or, when they are doing major maintenance work on the platform? This discussion 3 years ago kind of hints to it: https://help.nextdns.io/t/q6hb6qy/dns-nextdns-io-website-certificate-revoked.

    Though, it would be good if someone from Next DNS would address the reported issues with revoked certificates to even confirm or deny that Next DNS is at fault. Whitelisting the domain is not an option for me at this point, since I give my primary security software the benefit of the doubt, false positive or not. I like it to be overly sensitive when it comes to protecting my devices, and data 😁. 

    Does Next DNS even have a support email? Anyone, knows?

    With thanks,

       not sure why bitdefender would consider our certs as revoked. We’ll open a ticket with them.

       I've done an uninstall and reinstall, so I'll see if the issue continues.

       The reinstallation seems to have worked, though it's a different version. I'm not seeing the hundreds of notifications pointing to Next DNS as the issue. Also, not sure if it's related, but got a “not secure” error, and it pointed to an issue with a Next DNS certificate. Tried two browsers until the link worked over Tor. I use the custom Next DNS links in the browser, the Wi-Fi uses IP addresses with encryption, and my router is working with IP addresses through linked IP. The router needs DDNS configuration that I've not gotten to as yet. Maybe I'm over configuring 😁, but it's interesting to check, and see the logs by type. Also, figuring at least one of the configs will block if one is missed, if that is even possible.

       I'll do this when I get a chance: “Also, could you please provide a https://nextdns.io/diag”

       Why doesn't the executable have not NextDNS as the verified publisher? Windows blocked it from running, saying “Publisher:  
      Unknown publisher “.  What the application's purpose?
