    Hi Alex, Here the Umbraco trace log:

    @mt":"Connection ID \"{ConnectionId}\", Request ID \"{TraceIdentifier}\": An unhandled exception was thrown by the application.","@l":"Error","@x":"Microsoft.Data.SqlClient.SqlException (0x80131904): Cannot open database \"MYDB_11\" requested by the login. The login failed.\r\nLogin failed for user 'IIS APPPOOL\\MyAPPP'.\r\n   at Microsoft.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, UInt32 waitForMultipleObjectsTimeout, Boolean allowCreate, Boolean onlyOneCheckConnection, DbConnectionOptions userOptions, DbConnectionInternal& connection)\r\n   at Microsoft.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject,"Connection ID \"{ConnectionId}\", Request ID \"{TraceIdentifier}\": An unhandled exception was thrown by the application.","@l":"Error","@x":"

    i using same connection string with my umbraco 10 but different DB

     "umbracoDbDSN": "Server=H8190431715VM\\SQLEX17;Database=MYDB_11;User Id=myuser;Password=myPass",

    i also try add

    "Server=H8190431715VM\\SQLEX17;Database=MYDB_11;User Id=myuser;Password=myPass ;Trusted_Connection=True;MultipleActiveResultSets=True;Encrypt=True;TrustServerCertificate=True

    but still blank page error 500, and on trace log write same error report,

    (note: my IIS site binding using IP and port 89 (http://104.x.x.x:89))

    Hi Yahya,

    Does the SQL user definately have permissions on the database? and are they in the db_owner group for that database?

    I have the same problem. Connection to SQL server is ok, because I can login into back office, but If I open front end - I have blank page. The same happens if I deploy it to azure.

    Can you connect to that SQL server using MS SQL Management Studio and the credentials your using above?
