Looker Claim Broken - 'Problems with the connection' error

[jillian]

Hi there, 

Without any changes being done, I suddenly came across broken reports on my Looker this morning. Kindly find screenshot below. 

I am not able to even see the queries. Can someone assist with the below error? And, if there is a possibility to retrieve these queries or should I redo these dashboards from scratch?

When I click on ‘Edit’ for the dashboards ‘Not Working’ it says ‘Claim is broken’. There has been no change in Ownership either.
