Cannot conect to my aws postgress database in RDS
I created my Postgres database in AWS but it has connection timeouts every time I try to connect (using JDBC or pgadmin). I even added security groups but that didn't help.
Since I'm new in AWS I really have no idea what to do. Should I check any logs or I missed something during set-up?
Some things to check:
- Database was launched with
Publicly Available = Yes(Done!) - Security Group permits inbound access from your IP address or
0.0.0.0/0(Done!) - DNS Name resolves to a public IP address (I checked, it does!)
- Database was launched in public subnets (Defined as having a Route Table entry pointing to an Internet Gateway)
- Your network permits the traffic (can test on different networks, eg Home vs Office vs Tethered via your phone)
I tried connecting from my computer and it timed-out too, and I know that my "network permits" such traffic.
Therefore, it seems likely that the database was launched with a subnet group that contained only private subnets, which are not reachable from the Internet.
Update:
It appears that the database has been launched with a Subnet Group that contains private subnets rather than public subnets.
If you have not yet connected to the database / stored any data, it would be easiest to:
- Delete the current Amazon RDS instance
- Create a Subnet Group that contains public subnets
- Launch a new Amazon RDS instance using the new Subnet Group
For security, you should adjust the Security Group to only allow access from your IP address (removing the entries for 0.0.0.0/0).
