The SSL certificate for StackExchange's Imgur image host seems to have expired today. Going to https://i.sstatic.net/ yields this page in Chrome:

(posted on regular Imgur, for obvious reasons)

Here's a picture of the certificate details:

As the images show, the SSL certificate expired today. This is causing problems throughout all SE sites, including chat.

On the Q&A sites, load times have increased significantly (although I'm not sure how closely connected that is to the expired SSL), and most images in questions and answers won't load:

In chat, since most people use Stack Imgur to host their avatars, it's a disaster, as there are almost no images that can be loaded:

Sorry again if this is off-topic, but I wanted to announce it/ask for it to be fixed if that's possible on the SE side.

Edit: Back up! Thanks SE and Imgur for getting this resolved so quickly.

  • They renewed it only for 12 days: i.sstatic.net/572ND.png so prepare for another bug report in November 10th. Great way to make lots of reputation! /cc @Geoff Commented Oct 28, 2016 at 5:54
  • @ShadowWizard that looks like a different certificate. Issued in 2013. Guess we'll see. Commented Oct 28, 2016 at 9:53
  • @Sha Zac is correct: they didn't renew the cert, just swapped it for an existing still-valid cert. One hopes they'll get a new cert entirely before this one expires.

    @ArtOfCode I can't imagine that being too difficult, although this one was only valid for a year and was allowed to expire. Guess we'll see. Commented Oct 28, 2016 at 11:58
  • We'll see indeed, guess imgur try to save money, or just being too lazy. In 12 days we'll know better. /cc @ArtOfCode. Commented Oct 28, 2016 at 16:40
  • @ShadowWizard I personally don't see the point of having HTTPS in the first place, but then again I'm not a security expert. Commented Oct 28, 2016 at 17:11
  • @Zacharee1 part of the overall https support for Stack Exchange. If someone browse meta.stackexchange.com and the images are http only (not https) it will cause warning to appear, or even the images to not show, depends on the browser settings. Commented Oct 28, 2016 at 17:20
  • @ShadowWizard I thought full HTTPS for SE was a long way off. Is this just future proofing? Commented Oct 28, 2016 at 17:21
  • The reason it is long way off is the meta sites, as far as I know. Supporting https to meta sites under stackexchange.com domain requires changing the whole system and use totally different sub domains. Commented Oct 28, 2016 at 17:23

    This is all explained in this blog post by Nick Craver and the per site meta issue is reported and explained here. Commented Oct 28, 2016 at 17:38

We have contacted imgur and they are fixing this as we speak.

Thanks for the report.

  • I have the same problem now with one of my providers: Issued by: allot.com, signed by an untrusted user.
