Hi, I always visit this forum normally but today (29/09) since afternoon I'm not able to access through Chrome, It shows this message:

Well the clock is right from Brazilian Time. I can visit every other site except this one. By the way to post this message I'm using Firefox.

Thanks.

It's funny that Firefox works, but Chrome doesn't; considering both browsers implemented said security.

It has to do with SSL, where it seems Chrome doesn't think you have a secure connection.

The problem does lie with you however and there are a couple of things you can do to fix it (I'm not entirely sure what exactly.)

The fact other sites work is irrelevant since the issue only exist after the certificate of a site expires. Chances are the other sites you've visited hasn't had their certificates expired recently as most certificates are usually valid for 1-2 years at least. Unless it's LetsEncrypt, then it's valid for 3 months.

Well but it's weird that the message says:

> A private connection to forum.dlang.org can't be established because your computer's date and time (Thursday, September 30, 2021 at 9:57:20 AM) are incorrect.

But the date and time are correct for my region.

There is even a button labeled: "Update date and time", which I clicked but nothing changed.

Since this started yesterday after years accessing this forum, couldn't it be something wrong with your Certificate?

Thanks.

Unfortunately no. At least I can access through Firefox.

Thanks.

I think it's your computer.

Make sure that the timezone is set correctly.

It's possible that some security software/middleware is MITM-ing the TLS connection and injecting its own certificate, though that seems less likely to me.

Well it might be my PC but it's not the timezone or clock problem.

Strangely now I'm getting a slightly different message as before but with a new option called: "Advanced", clicking over it shows another message: "Proceed to forum.dlang.org (unsafe)".

Clicking on this let me go here, but the "https://" is crossed and when I click over it says: "Server certificate is not yet valid" and "Server certificate is not trusted".

But please don't bother with this because It may be something here, I asked before just to be sure if it was something with this site since was only happening here, but now I see this on other sites as well, or a message like this:

> "You cannot visit www.anothersite.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later."

Thanks again for trying to help.
