I have a webpart which is deployed correctly in test environment but it fails to deploy when we deploy it in production environment 2013.
structure is as follows
Web front end server 1 load balanced
web front end server 2 load balanced
Application server1 application server2
I am using Application server 1 to deploy the webpart . it deploys fine on that particular server when i see in farm solutions but it fails for other 3 saying web.config is invalid. where i am going wrong?
