the title explains it all

click here to download and look at the image yourself.
when i continue it it, it redirects to en.scratch-wiki.info
try it yourself here
edit: it was fixed
edit 2: it was not fixed, i pressed continue so it will ignore at next visit

Cannot replicate on Firefox 89 or Safari 14 for macOS, maybe it's an issue with your side because it says that your computer clock may be inaccurate?

And I think it's ok since it just redirects you to https://en.scratch-wiki.info

i did this on edge (chrome) and it shows that it expired, i have a windows XP VM without the google certificates, and firefox ignored the warnings, but chrome did not, so it only affects chrome and chrome based users, not firefox.
also, my system clock is correct according to one of the other devices i have
thanks for trying
note: i am on windows 10 so other people cant replicate it on other systems like: Mac and Linux

Can't replicate. Also redirects me to https://en.scratch-wiki.info/ . Same on Edge and Firefox.

Probably this ^ or something else that has to do with your computer.

i can reproduce this issue.

incase others have trouble reproducing the issue, make sure it's https://wiki.scratch.mit.edu if you forget the s, it'll work properly because it's going over http.

it should be theoretically simple to renew an https cert right?

I didn't get the same error. Mine was “The webpage could not be loaded because the server could not be found.”

that was my bad, i added a comma at the end of the link

I'm getting redirected to en.scratch-wiki.info with no problem.

I can replicate this on an Apple Watch.

jeffalo to the rescue! can replicate now, macOS 11.4, Firefox 89

Yes, can replicate on Windows 10, Edge 91, Chrome 91 (ew) Firefox 89, and Firefox 78 ESR
Edge:

Chrome:

Firefox (RR):

Firefox (ESR):

I think I was one of the 1st people to report it. I did so on the forum topic, and only the ST can fix it, as per what @jvvg said.

Edge, Safari, and Firefox are all better than chrome and can replicate this issue just as easily.

Reload.

Thank you kind sir, it works!

Thank you. It works now.

For the curious, here is what happened:

• The wiki was turned over to the folks behind scratch-wiki.info in 2018

• A redirector on a standalone EC2 AWS instance was setup and configured to return redirects to scratch-wiki.info with HTTPS and HTTP supported

• This host had letsencrypt installed on it and it has run on its own since that time

• Since then, letsencrypt has evolved and no longer supported the version of `certbot` running on wiki.scratch.mit.edu

• That stopped working (after working fine for the last 3 years or so) but we didn't notice until this forum post

• We have a check on HTTPS for wiki.scratch.mit.edu by a third party vendor, but this did not alert us in a timely fashion.

• Fixing it was just updating to the most recent version of `certbot`

Which vendor was it? I'm curious
