Connection lost between excel file and power BI service

Hi!!
Recently i have created one excel file which i placed in One drive for Business. I have used this file to develop reports and Dashboards from Power BI web service.
Yesterday while working on the One Drive, by mistake I CUT and PASTE same file to Sharepoint. I corrected my mistake and placed same file back to One drive for business (without any modification). After this instance i updated some of the contents in same file and tried to refresh the Power BI reports/datasets but it is not updating in power BI service. For your information, I am not getting any error message for connection lost but same time nothing is updating.
Kindly suggest what can be done to bring the connection back as i have spent whole lot of time in preparing this report and Dashboard.

Thanks
