Solved: Connecting Compute Engine instance to AWS RDS inst... - Page 2

Hello,

I'm currently running into an issue attempting to connect an application running on the GCP Compute Engine to an RDS running through AWS. Each time I attempt to connect to the RDS instance I receive the error: (2003, "Can't connect to MySQL server on '<endpoint-name>' (timed out)"). The application works fine when run on a local machine and not a GCP Compute Engine instance.

I was wondering if this was something that could be resolved in order to have the two instances talk to each other properly.

Thank you,

Claire

Hello @claireaw ,Welcome on Google Cloud Community.

Did you've added firewall rule, allowing 3306 port for VPC and VM inside this VPC?
1. Go to your Compute Engine -> Pick VM from which you want to connect with AWS RDS.
2. Search for Network interfaces and click on Network

3. Then go to FIREWALLS -> Add FW rule -> For testing purposes set as on screenshot

4. Wait 1-2 minutes and try to connect to your RDS.
