Yahoo Mail problems today

EDIT: It's working now. I think the URL in the shortcut button no longer works and need to be updated.

====================================

Since last evening, on my Windows PC using Chrome, and my Macbook using Firefox, when I attempt to use Yahoo Mail I get this error message:

Server Connection Closed

Description: The server requested closed the connection before the transaction was completed.

I have checked some monitoring sites and am not seeing this mentioned as a problem right now.

I am able to access my mail account on my phone.

Are any of you having this problem?
Any advice?
