Hi Mike!

It's not like they blocked it. The site is not showing a proper certificate, it's malconfigured and the browser let's you know that. You can ignore the warning, though I would not recommend it. This should be fixed by their administrators.

You might send them an email to report the problem, it might help.

Yes, the site certificate has expired. see screenshot

Thank you both for your reply, I sent them an email, with a picture of the warning, I also called them, they are closed today, so I left a message.

I hope that they have not been hacked, if so I just let the hackers have my email.

I will let you know what the outcome is when they get back to the office on Monday.

Mike.

They eventually sent me a message, stating that their website, went down for a short time over the weekend, it must have been unscheduled or they would have told their clients.

It is OK now.

Mike.
