This site isn’t being proxied by Cloudflare so it’s not a Cloudflare or proxy issue.

Since this cert error includes the name of the ISP in question, it’s something related to the ISP and the visitor should contact their ISP to determine the issue / resolve.

Thanks for your reply. I’m afraid that I have to contact someone over Telstra as the owner of the business as the issue is with all Telstra users, not only one. Especially with their wifi connection at home. That’s why I’m thinking that this on the macro scale of things could be not only related to one customer but to all of them.

It very well could be all users of that provider, but the issue is at the provider. You would need to contact them to understand why they have chosen to block the website.

Like nation states an ISP can do whatever they want to a large degree.
