Connection String is not working on AWS - asp.net

Question

I am working on a web API application on visual studio 2017. I have published the web application on my local IIS and everything is working fine, but when I publish it to IIS on AWS instance (with windows server 2012) the connection string keep giving me errors and could not manage to connect correctly.
The connection string is:
<add name="TouchlessDbContext" connectionString="metadata=res://*/; provider=System.Data.SqlClient;provider connection string="Server=WIN-FBNRCF4UTP3\SQLEXPRESS;initial catalog=TouchlessDB;integrated security=True;User Id=sa; Password=Password01;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
and here is the error I am getting from the browser:
{"$id":"1","message":"An error has occurred.","exceptionMessage":"The underlying provider failed on Open.","exceptionType":"System.Data.Entity.Core.EntityException","stackTrace":" at System.Data.Entity.Core.EntityClient.EntityConnection.Open()\r\n at System.Data.Entity.Core.Objects.ObjectContext.EnsureConnection(Boolean shouldMonitorTransactions)\r\n at System.Data.Entity.Core.Objects.ObjectContext.ExecuteInTransaction[T](Func`1 func, IDbExecutionStrategy executionStrategy, Boolean startLocalTransaction, Boolean releaseConnectionOnSuccess)\r\n at System.Data.Entity.Core.Objects.ObjectQuery`1.<>c__DisplayClass7.<GetResults>b__5()\r\n at System.Data.Entity.SqlServer.DefaultSqlExecutionStrategy.Execute[TResult](Func`1 operation)\r\n at System.Data.Entity.Core.Objects.ObjectQuery`1.GetResults(Nullable`1 forMergeOption)\r\n at System.Data.Entity.Core.Objects.ObjectQuery`1.<System.Collections.Generic.IEnumerable<T>.GetEnumerator>b__0()\r\n at System.Data.Entity.Internal.LazyEnumerator`1.MoveNext()\r\n at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)\r\n at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)\r\n at Touchless.Web.Api.Common.Filters.BasicAuthorizeAttribute.HandleAuthorized(HttpActionContext actionContext, AuthenticationHeaderValue authHeader) in D:\\Touchless.Web.Api\\WEB-API\\Touchless.Web.Api\\Touchless.Web.Api.Common\\Filters\\BasicAuthorizeAttribute.cs:line 60\r\n at Touchless.Web.Api.Common.Filters.BasicAuthorizeAttribute.OnAuthorization(HttpActionContext actionContext) in D:\\Touchless.Web.Api\\WEB-API\\Touchless.Web.Api\\Touchless.Web.Api.Common\\Filters\\BasicAuthorizeAttribute.cs:line 49\r\n at System.Web.Http.Filters.AuthorizationFilterAttribute.OnAuthorizationAsync(HttpActionContext actionContext, CancellationToken cancellationToken)\r\n--- End of stack trace from previous location where exception was thrown ---\r\n at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n at System.Web.Http.Filters.AuthorizationFilterAttribute.<ExecuteAuthorizationFilterAsyncCore>d__2.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__1.MoveNext()","innerException":{"$id":"2","message":"An error has occurred.","exceptionMessage":"Cannot open database \"TouchlessDB\" requested by the login.

Could you please help me to solve it?
