Dashboard will not load

I have an issue where my dashboard wont load. The page just has the spinner. What can i do to trouble shoot the issue?

Hi,

Thanks for the report. Can you use your browser debugging tools to see which request is hanging? Are there any errors in the event viewer on the Octopus server?

There was a long running retention policy task running. I canceled that it works now.
Looks like it was running for 15 hrs.
