Design Studio Restarts automatically

Hi All,

I am facing a weird issue in Design Studio 1.3. It gets restarted automatically whenever I try to insert a new datasource. It throws the below error before it gets restarted. "Automatic re-logon has failed (see error log for details)" Once it gets restarted, again throws the same error when tried to insert the datasource. It repeats the same. Please help me resolve this issue.?

Please help.

I did not find the right solution from the Internet.
