In my current setup, I’m hosting an RDS on AWS, in a private network (so it isn’t publicly accessible)

Using AWS SSM manager, I can overcome this, and run it locally:

aws ssm start-session --target <redacted> --document-name AWS-StartPortForwardingSessionToRemoteHost --parameters '{"host":[<redacted>],"portNumber":["5432"],"localPortNumber":["5500"]}' --region <redacted>

It works perfectly with DOTNET, and JetBrains DB connection. I just input a connection string like:

jdbc:postgresql://localhost:5500/postgres, give it my username and password, and voila.

For DOTNET, I just use the connection string:

Server=localhost;Database=;User Id=;Password=;Port=5500

But, for some ODD REASON, PgAdmin just will not connect to this port forwaded instance.

I open PgAdmin -> Register -> Server PgAdmin Photo

I input all of the fields like I do for DOTNET / JetBrains:

Filling in the fields

But, it just doesn’t seem to work.
