Tried connecting with the end point using Filezilla (For Example: mysqldb.asdfghasd.us-
center-9.rds.amazonaws.com) failed after the instance was mapped to the DNS.
Had the following message;
Command: open "ubuntu@PUBLIC_DNS" 22Error: Connection timed out after 20 seconds of inactivityError: Could not connect to server
Solution: In the Host field, use the Elastic IP that is assigned to the instance.
Connecting with the Elastic IP it works. Took about 2 hours to figure this out. But a lesson well learnt.
