I’m facing the same issue, which is that the certificate has expired.
Expiration date: february 28th 2018
Today is the 1st march2018

Is this “bug” part of the game ? :) :)

PS: To avoid this, I have changed my system date for a few days in the past!

You can access to the website with Internet Explorer or Microsoft Edge

The free SSL certificate of HackThis has expired maybe the website was hacked or just new update from Firefox and Chrome ?`

That’s a very big issue with priority @flabbyrabbit

Let us know if the website has some malware who can infect us.

Everyone, flabbyrabbit told me to tell you that everything is fine. This is not a hack. I repeat: This is not a hack!

How to Delete HSTS Settings in Firefox:

We will cover two different methods for deleting HSTS settings in Firefox. The first method should work in most cases but we also included a manual option if needed.

Close all open tabs in Firefox.  
Open the full History window with the keyboard shortcut Ctrl + Shift + H (Cmd + Shift + H on Mac). You must use this window or the sidebar for the below options to be available.  
Find the site you want to delete the HSTS settings for  you can search for the site at the upper right if needed.  
Right-click the site from the list of items and click Forget About This Site.This should clear the HSTS settings (and other cache data) for that domain.  
Restart Firefox and visit the site. You should now be able to visit the site over HTTP/broken 

that worked for me at least

:3

broke my 109dayslastingeverydaylogin for that :@

You can connect with In-Private mode or on your phone ;)

It broke the 109 login days because it cleared other catch data which was stated in my last post

That includes login days

Yeah… no. Consecutive days are not stored client-side.

You can add an exception if you go to about:support, click open directory, and edit SiteSecurityServiceState.txt. Remove all lines which mention hackthis.co.uk. Then restart firefox.

It’s a cert issue. I e-mailed the site owner to maybe look into this. I ended up having to use edge myself to get in since everything else I have has idiot guards I guess (chrome and firefox).

The thing is just saying the cert expired/isn’t valid.

When will the certificates be fixed?

I thought it would’ve been done by now. Only the site owner knows.
I hope soon.

This site SSL server certificate was expired thats why it was down. You can view more by clicking on secure in chrome.

Just in case you don’t notice it: the certificate has been renewed.

Don’t forget to remove any security exceptions you might have added.

R.i.p my consecutive 94 logged in days

Too bad, but you could have logged in anyway?
