I am trying to access SQL Server 2016 from outside of my network but each time I try I get this error message.
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (.Net SqlClient Data Provider)
The ports on my managed firewall are open, and I have also turned off Windows Firewall too in the event that this was the blocker but I am still getting the issue.
I have checked the Configuration Manager and its listening on port 1433, however, when I look at netstat -an I dont see this port is being listened on so suspect this may be where the issue exists.
A question I have is if configuration manager says its listening on this port, why is it not showing in netstat?
Also, what else can I try in order to gain access.
