.net core MVC web application is not connecting the database

M.V. MADHANA MOHAN 1

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Usually this error means the client cannot find the database server. You did not share enough information for the community to know why the connection does not work.

A common situation on these forums is a developer uses a local database instance while developing the application. Once deployed to a web server, the database connection errors because the database does not exist on the web server. The standard solution is deploy the database to a database server and update the connection string to use the remote database server.
