Hi Adhav, I'll see if I can find someone to address this question. From just the error message, this sounds more like a server configuration issue than a Deployment Manager issue. In the mean-time, can you describe what you're doing at the time? Is it when you click "Start Deployment" for example? Also, depending upon the version of Deployment Manager, you may have an Actions > Diagnose pipeline option. Please run that and send along a screenshot of the results.
