Looking for a fix


I get the below message Ad Nauseum. Looking for a fix to rectify...

msedge.exe attempted to establish a connection relying on an untrusted certificate to wpad. We blocked the connection to keep your data safe since untrusted certificates are issued by unrecognized Certificate Authorities.

Any Help is a Help!

    Hello @Flawdaboy and welcome to the Community!

    If you are getting this message, then it's most likely paired with the "Suspicious connection blocked" pop up triggered by the Online Threat Prevention module. If this is correct, head to the article below to find steps on how to tackle this:

    Let us know how it goes.

  • Thanks. It kind of helped. The message seems to be generated when Microsoft Edge goes out to look for something. I never use Microsoft Edge. I only use Firefox. Conversely, when I do go to sites via Firefox that may have certificate issues, that's on me and understandable.

    I guess I want to stop Edge from doing what it's doing without me even being on it. For the record, I have no extensions built into Edge because I don't use it.

    I started getting this tonight but I'm not even using Microsoft Edge browser. I'm using Firefox and I've had three pop ups in the last 40 minutes.

    msedge.exe attempted to establish a connection relying on an expired certificate to We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk.

    Add to exceptions


    Searched for info on Google, got this. is a subdomain of DNS resolution of points to with a location in Seattle, Washington US. Parent domain registration belongs to Microsoft Corporation, registered through CSC Corporate Domains, Inc.. The server responds with an SSL certificate issud by Microsoft Corporation to Microsoft Corporation under the common name *

    Cloudflare security assessment status for Safe ✅.


    I'm just gonna add it to exceptions but it's weird this pop up happens when I don't even have Edge open.


    I'm having this exact problem today and it is getting annoying, I have 16 notifications so far. It started 4 hours ago and everyone that I know (that have Bitdefender) is having the same problem.

    Hello @Jota & @STRATOS55,

    This is a known situation that has been reported intensively on the forum in the past days. Below I have shared one of the relevant threads where the reason behind this is explained:

    There are also some instructions that you can follow to address this behavior, but otherwise I think this is something that microsoft needs to sort out..

    Surely to goodness adding it as an exception should stop these popups or what's the point of adding exceptions?

    The site is legit, just lacking a certificate.

  • Alexandru_BD


    Microsoft owns the domain, and the SSL certificate recently expired, but there is no danger of malware or harm to the devices. This type of notification is triggered by the Online Threat Prevention module whenever the website you are trying to access doesn't have an SSL certificate (HTTPS) and it's not safe to access, and the alert is also triggered when you try to visit a secured website (HTTPS) with an invalid security certificate and this is what actually happens here.

    I understand that several community members have raised concerns about the certificate issue on Microsoft forums, and most probably they are working on a resolution and will release a fix soon.

    For further information, you can also contact the Microsoft Support Team.

    It has been noticed that adding exceptions for OTP can be an effective way to stop the pop-ups.

    I hope this gets resolved asap.

    Thanks, but this is not an adware problem, it is a problem of Bitdefender and MS, hoping that they solve it soon, any machine using bitdefender is having this problem at the moment, at least 20 machines I've noticed, meanwhile machines and vm's without bitdefender have no problem, I hope that Bitdefender actual employees and MS solve this problem with certificates soon.

  • Alexandru_BD

    @STRATOS55 you are right, this is not an adware problem, as the notification trigger was later revealed. At the time Gjoksi commented, everyone here was trying to figure out what was happening and as soon as we discovered that concerns have been raised by several users regarding this certificate issue on Microsoft forums as well, it became clear it was a problem. The good part is that there is no actual security threat there.

    It’s likely that Microsoft is already working on a solution, and we anticipate a fix to be released in due course. You can track the ongoing discussion and progress on this matter through this link:

    Thank you!

    Is this the same problem? Getting notices indicating that it is Firefox that is attempting to connect - not EDGE.

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

  • Alexandru_BD

    Hello @llsutton and thanks for joining us here.

    As the notification explains, this is a different scenario where the certificate in question is not expired, but was issued for a different web address. The feature responsible for the detection is the Encrypted web scan available in the Online Threat Prevention security module. You can find out more information about this detection and possible remediation steps by clicking on the link below:

    Let us know if the issue could be solved and if the notification is still present afterwards.
