Error querying data model and X509 certificate has expired or is not yet valid

All the dashboards in our Sisense server are not working today with the Error "Error querying your data model"!

When I tried to log into the Sisense CLI on the Sisense server, I got the following error message.

 

Could you help check what is wrong?
