Probably a problem on your side. My browser says the certificate is valid until December 31st and is trustworthy.

On my setup the website and certificate is fine. Renewed on 1st October, and valid through the end of the year.

Is this still occurring for you? I know there were some issues with an old Let's Encrypt root certificate expiring recently - are you able to update your OS and/or browser certificate store? What OS and browser are you using?

It is yes ... but since I posted I have had the same issue on a few more websites.

I am using an outdated chrome browser, which I fiddled with, on a vanilla windows 7 pro installation with next to no updates.
Pretty sure it is on my side.

I will check on my (also) outdated firefox browser in a bit and an up to date non modified internet explorer or something in a bit.


ps: For now, continuing beyond the warning still seems to work fine


Edit: posting from firefox ... tt-forums has a green lock and I should've checked that first I guess ...

So I've looked a bit deeper into my 'issue' ...

Seems the tt-forums certificate got updated and is valid but the two above did not and are no longer (@see attachments)
Not sure what to make of this or how this happened/is happening ... don't put too much effort into this as I did mess with my browser and OS very mucho ... at some point I had websites complaining about my system time not being synced (due to disabling auto 'updates' in my services; they are somehow related ... LOL).

Anyhoo just felt like giving you some more data to go by?

The let's encrypt certificate did indeed expire and was not renewed as was the other one but I have bo clue why or how ... hope that helps but if not ... Hakuna Matata, I'll live and it's just me so far

Edit: my browser is Chrome Version 78.0.3904.108 (Official Build) (64-bit) ... just to be complete

I’ll check if we’re serving the correct root certificates - it’s all automated but maybe there’s something wrong.
