They switched to this one.

IF you use brave, the analytics on peakd are said not to work.
So, I hadn't looked in a long time.

It appears that the error could be a node issue that will 'fix itself' when somebody from peakd sees it.
Seems that they have added lots of blockchain data, but no peakd data.
That might be the brave issue.
