I have a new web app in Azure that im trying to connect to my on-premises SQL server and following the instructions on this link.
I have opened up our firewall and configured an IP address to route it through port 1433.
I have setup, in Azure a Biz Talk hybrid connection (i have set the host name to the IP address and said port) and the Connection manager has been installed locally.
I have set the following connection string in web.config
<add name="MyContext" providerName="System.Data.SqlClient" connectionString="Data Source=<IPADDRESS>\<SQLINSTANCE>,1433;Initial Catalog=MyCatalogue;
Network Library=DBMSSOCN;User ID=<USER>;Password=<PASS>;MultipleActiveResultSets=True" />
I have confirmed that the said IP address is responding on port 1433
I am getting the following error [Win32Exception (0x80004005): No such host is known]
Can anyone help me please with what I might have missed
