Is this caused by Avast?

I did a single click and the screenshot shows the result.

What browser are you using ?

If you right click on the link does your browser give the option to Save Link As (mine does, see attached) or similar wording ?

I’m using Firefox and it doesnt give me that option. Took it into Edge and got this:

I have the latest Firefox version 93.0 and the right click menu options haven’t changed in a very long time and the Save Link as… option has been there for as long as I can remember.

I have never used Edge, I have avoided it from day one, so I can’t comment on that.

But as r@vast mentioned he can connect to wsfa.com also without issue, so no avast alert either.

Something very strange going on.

tried right click and gave same error

Are you using any security based add-ons in your browsers ?

Some such as Firefox have an option to enforce https connection and you get the occasional error if the site doesn’t have https available (though this shouldn’t be the issue with this site).

Your last image looks more like a windows Defender style error as windows now has checks on downloads (which I disabled to avoid possible conflict).

Other than this, I’m pretty much out of ideas.

It isn’t an Avast message.

You can also right-click the download link for the CA certificate, select “Copy link address” and paste it in a new tab. That should allow you to download the new certificate.

Had this exact problem and this helped: https://techglimpse.com/dst-root-ca-x3-expired-certificate-error/ - the Step 6 is important because I originally imported it in a wrong folder.

i get the same error - can’t connect to that site

Download the certs on another device and copy them over.

every link people have sent wont allow me to go to the site.
can anyone download the certs and send them in a ZIP?

As said, download the certs on another device and copy them over.

Download it to a flash drive once downloaded, take that flash drive to the affected system.

i have this one computer and flash drive, nothing works. i give up

How about family/friends/neighbors, can’t you download it there…?

just got the certs from someone, downloaded, installed, rebooted, no change

Is it possible that you imported the certificate in a wrong directory? I’m asking because it happened to me, and then I followed this article (step 6) and it started working: https://techglimpse.com/dst-root-ca-x3-expired-certificate-error/

that link caused the same bad cert error

here are the instructions for installing the new, updated root-certificate-file that is needed, according to “techglimpse.” the file’s name, from “letsencrypt,” is “isrgrootx1.der.”

doubleclick the file to install it and, when installing it, choose “Place all certificates in the following store” and choose “Trusted Root Certification Authorities.”

incidentally, the techglimpse article mentions that up-to-date versions of the firefox browser are not affected by the issue since firefox has its own set of root-certificates, which would be up-to-date.
