I have tried everything to be able to connect to my MS SQL Server 2012 remotely.
I have read and setup everything like Kyralessa wrote in his answer HERE.

• Enable TCP/IP done
• Add 1433 TCP Port done
• enable SQL Server Browser done
• Add 1433 TCP, 1434 UDP ports to Windows Firewall done
• Add sqlserver.exe and sqlbrowser.exe to Windows Firewall done
• Use ip address and port to connect done

I am still receiving an error message: Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attampt failed because the connected party did not properly respond after a period of time.

Nothing works
Do you maybe have any other solution I could try to solve this problem?
