DataStudio can't connect / Supermetrics ad connector

Hello, yesterday I set up the Supermetrics ad connector to import FB and Google Ads data. Today, I get this error "Error fetching FA results: aaa (Supermetrics request ID: kc43mtnMf3ItCT88igb6WfDFANmJKNx9).

Error ID: 509b771b"

I tried Googling to no avail. 

Thanks in advance!
