Appian RPA Online Training Course - no longer working

Hi, the online training course link (Appian RPA) is no longer working. It was working until yesterday. 

https://academy.appian.com/#/curricula/5162ffb8-47b5-4516-a127-353f0156a7e4

Getting a message: We're so sorry! We could not locate this course. If you believe you should have access to this course, please contact your system administrator. I am able to access other training links. If i try to access it thru learning journey I am getting a blank screen

any help will be appreciated.. I will keep checking though every 30 min

thanks
