I have created an EC2 instance which is running sql server. This is not RDS, it is an standard EC2 instance.
I have no trouble connecting to the database from another EC2 instance connected to the same domain. However I am trying to connect an external server running Windows 10 to the database and it times out without being able to connect. I have turned off the firewall on my server and opened the security group in AWS to All Traffic from all the world to rule these out, but I am still unable to connect.
Does anyone have an idea where I can go from here? If it's not the firewall or security group settings, what else could be stopping me from connecting to the database from outside of AWS?
EDIT: This is the default SQL instance. SQL Browser is running but shouldn't be needed to connect. Also all protocols are enabled in the Configuration...
