MYOB Accountright Certificate error

I'm getting the same window. Could someone advise us.
I have checked our internet connection, our clock is correct, cleared browser history, cached and cookies, restarted my PC and nothing works. 

A colleague tried to login from his machine and got the same screen.

What is causing this? Please advise, thanks!

while its all good and well to say to use the web browser as a workaround we can't do our invoicing on the web browser due to the following: This invoice is read only because the layout isn't supported in the browser. Switch to AccountRight desktop to edit this invoice.

WHICH is why we use the desktop! 

Received below message.

It seems an issue from MYOB's end.

Hoping to receive an update soon. 

Same issue here as well.

I have the same problem 

We are having the same issue..

Temporary workaround: If you encounter the certificate warning page, type thisisunsafe (no space) in your browser to bypass the warning and allow you to proceed.

MYOB let their certificate expire for single sign-on.

Considering I can't access my custom reports online, that doesn't help me.

We are having the same issue here in Perth. We have contacted other businesses using MYOB and they are having the same issue. We have used different computers, different browsers and cannot log in to the App. I thought it was a Firefox thing but it isn't. It is happening when accessing via Edge as well. We can log into the web browser but it is so clunky and slow.
