Deployment Manager errors while running the plan

This issue is happening because certificates are imported into Keystore files unexpectedly.

To resolve the issue, reset the Keystore files from another environment by following the below steps:
1. Shutdown the Non-Working environment. 
2. Take a backup of the <install>conf\server\security directory in the Non-Working environment. 
3. Login to the Working environment. Copy all the JKS files from the <install>conf\server\security directory. 
4. Paste them in the Non-working environment's <install>conf\server\security directory. 
5. Restart the Server after making this change. 

This will reset and resolve the SSL issue encountered  by the Deployment Manager.
