SQL Server Connection Issue

0

I setup a new SQL Server instance from scratch, using the standard setup workflow . No additional configurations; pretty much out of the box setup with the endpoint publicly accessible. When attempting to connect to the database I get a MSFT Server Error: 53 (could not open connection). Makes zero sense. It's definitely setup to be accessible.

At a loss. Any thoughts?

Check your default security group allows 1433 inbound from your IP address.

I say default as this is the SG assigned to your RDS instance in your screen shot.

Also make sure your RDS instance is in a Public subnet too.

  • Yup. That was it. Thanks Gary.

  • Thanks for confirming this worked for you.

  • Sorry, but would you be so kind as to tell me which of these was the resolution for your connection issue?

    • Check your default security group allows 1433 inbound from your IP address.
    • Also make sure your RDS instance is in a Public subnet too.

    And perhaps you be able to point me to where I might find more details on the setting changes that were required?

    I'm a complete newbie here in AWS... just wanted to quick setup a SQL Server RDS for quick "proof of concept" of something but sadly I'm struggling to make a connection to it from outside. Well, that's not quite accurate. I HAVE successfully connected to it via SSMS but attempts at doing the same from appsmith have failed. Thus I suspect it has to do with allowing their IP's but from what I can tell I'm done that.

    Many thanks!
