[SMARTCRAWL & WPMU DEV DASHBOARD] issue with api?

16th March all the API went down on my sites. There used to be an Analytics graph in the dashboard drawn in from the Report in Hub.

Since the 16th March it seems to have lost its connection and I have the following error in SmartCrawl:

Your SEO crawl has timed out due to an unknown error.

Could this be related to the last wpmu API issue? How do I get this working again on my site?
