"Warning: Issue establishing a database connection!" but the connection string is correct

Question

I am migrating a .NET application from one server to another. All I did was zip and move the compiled project folder from one server to another. Then I edited the connection string with correct server name, username and password. On the back end I tested the username and password and everything works fine. Also check the permissions. Nothing is wrong. But the site login is still not working and is throwing Warning: Issue establishing a database connection! error when I enter username/password and hit login. Any help?

Answer 1

Do you have any weird characters in your password that need escaping in your config file? Not that I want to know what characters you have in your password, of course.
