Question

Cannot connect to SQL Database. Please contact SQL server team for further support. Server: '20.81.184.76 1433', Database: 'Target', User: 'target'. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access.

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server), SqlErrorNumber=53,Class=20,State=0,

The network path was not found

Target Database is hosted on Azure VM

Answer 1

As the database is hosted on an Azure VM which is within a VNet, you would have to install a self hosted IR in a server within the VNet which would be able to access the database.

And use that SHIR via ADF to access the database :

You can also set up a private end point :
