SSL issue on https://mail-redirect.exercism.io

Hello,

The following service has SSL issue: https://mail-redirect.exercism.io

Certificate’s common name is invalid.

This service is used for in mail URLs.

Additionally the service is accessible in http: http://mail-redirect.exercism.io/ which I guess is not wanted.

@iHiD / @ErikSchierboom I think you want too take a look at this as mails links are kind of broken for the moment (sorry for the mention).

Jeremy will look at this when he’s back

It looks like the issued certificate is for “spgo.io” with various alt names related to this domain.

@homersimpsons Where are you seeing the https://mail-redirect.exercism.io URL?

And further, what email provider are you using? Does it convert http links to https ones by any chance?

@homersimpsons Where are you seeing the https://mail-redirect.exercism.io URL?

In the e-mail I receive from Exercism. But in fact it looks like the original link is http://mail-redirect.exercism.io.

And further, what email provider are you using? Does it convert http links to https ones by any chance?

It is Gmail, but it does not look like it is the provider that is converting the links. Where I noticed the issue it was on my phone (Android) where I use Firefox Focus.

So I think what is happening is:

  1. The email is sent with http:// link
  2. I click the link (still http://)
  3. Firefox Focus converts the link to https://, I just checked the setings and I have “HTTPS-Only Mode” enabled
  4. The invalid certificate makes it impossible to load

I think the service should be available under https://

OK. Thanks for all that info. We don’t control that service - its part of our email sending provider. So I’ll have to look and see what options are available. Thanks.
