Fortran-lang website security issue?

Dear all,

The following screenshots comes from me scrolling thought the following fortran-lang wiki:

Just wondering what happened, or is it my local problem.

Same connecting with Google Chrome. It says

This server could not prove that it is fortran-lang.org ; its security certificate expired in the last day.

Firefox also prints a warning for that web site.

Same here. I can have a look tomorrow. Github says at https://github.com/fortran-lang/webpage/settings/pages:

So it almost seems like a github issue with updating the certificate, unless something needs to be configured at our dns.

Ok, GitHub gave a better error message now:

I am not sure what changed. Investigating.

Ok, so using Managing a custom domain for your GitHub Pages site - GitHub Docs we can verify that the IP addresses are set correctly:

$ dig fortran-lang.org +noall +answer -t A

; <<>> DiG 9.10.6 <<>> fortran-lang.org +noall +answer -t A
;; global options: +cmd
fortran-lang.org.       14400   IN      A       185.199.109.153
fortran-lang.org.       14400   IN      A       185.199.111.153
fortran-lang.org.       14400   IN      A       185.199.110.153
fortran-lang.org.       14400   IN      A       185.199.108.153
$ dig fortran-lang.org +noall +answer -t AAAA

; <<>> DiG 9.10.6 <<>> fortran-lang.org +noall +answer -t AAAA
;; global options: +cmd
fortran-lang.org.       14400   IN      AAAA    2606:50c0:8002::153
fortran-lang.org.       14400   IN      AAAA    2606:50c0:8001::153
fortran-lang.org.       14400   IN      AAAA    2606:50c0:8003::153
fortran-lang.org.       14400   IN      AAAA    2606:50c0:8000::153

That looks good. I changed www from fortran-lang.github.com to fortran-lang.github.io, according to the docs that should be the right value.

I can’t see any other problem. I am also “verifying” the domain using Verifying or approving a domain for your organization - GitHub Docs, that worked:

and

From the error message, it’s the www.fortran-lang.org that was incorrectly configured, and I think indeed it was, it was poinging to .com instead of .io, so I am hoping that was it. We’ll have to wait 4h and then try again.

Ok, that was it, progress:

And I clicked the Enforce HTTPS and that also worked:

And the page is back on:

image1990Ă—934 91.6 KB

So the issue was that www.fortran-lang.org was pointing to fortran-lang.github.com instead of fortran-lang.github.io, I am guessing that has always been the case, but only now it actually failed at github, I guess they decided to put some extra enforcement of this.
