I am trying to manipulate db directly from pgAdmin4 but I cannot connect.
What I checked and did are
I read this doc and following https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ConnectToPostgreSQLInstance.html#USER_ConnectToPostgreSQLInstance.Troubleshooting
and input the information about the db instance as the doc does.
However I couldn't connect and I checked the security group. The VPC security group is like this.
What else should I check? I totally have no idea how I can fix this. The only concern is the password's current value is always going to be empty even after I set a password.
Anyone could help me? I have to connect and manipulate db directly.
