Script download fails at Intializing the test run in PC 11.0

I created a performance scenario with 5 scripts. 

All of those run without issues in VUGen. 

However, recently we are unable to execute the scenario in Performance Center. 

 

It fails while initializing the script at downloading the scripts step .....

While the QC log says the below message which doesnt give us any clue...

 

Can anyone help on this?
