Accessing the course " Overview of Neo4j 4.x"

I completed this course and was trying to download the certificate and I wasn't able to do so. Eventually, when I tried to refresh the page, I ran into the error shown in the attachment. "Error while loading the data, please refresh the page."

I tried different browsers and restarted my computer. I see this error once I sign in. Can someone please help?

Thanks so much!

I have the same screen as well.
