HTTPS issue: Browser claims connection is not safe

[1Maxnet1]

When I try to connect to https://project-osrm.org/, I get an warning:

My Setup: Firefox with HTTPSEverywhere and uBlockOrigin installed.

When I click show more information it sais:
"Websites bestätigen ihre Identität mittels Zertifikaten. Firefox vertraut dieser Website nicht, weil das von der Website verwendete Zertifikat nicht für project-osrm.org gilt. Das Zertifikat gilt nur für folgende Namen: *.github.com, github.com"

Translated to english: "Websites confirm their identity using certificates. Firefox does not trust this website because the certificate used by the website is not valid for project-osrm.org. The certificate is valid only for the following names: *.github.com, github.com"

According to Github this can be fixed with a simple DNS change to the A records : https://github.blog/2018-05-01-github-pages-custom-domains-https/

Unfortunately, I don't know who has admin access to project-osrm.org DNS records to make this change.

Page builds also provide a warning that the DNS records are out-of-date, so in any case this will need changing to continue using project-osrm.org

The custom domain for your GitHub Pages site is pointed at an outdated IP address. You must update your site's DNS records if you'd like it to be available via your custom domain. For more information, see https://docs.github.com/github/working-with-github-pages/configuring-a-custom-domain-for-your-github-pages-site.

https://project-osrm.org/ is now working.
