Not able to connect with external database on 3306 port

[FenilShah]

I am using amazon RDS in my application, and want to connect with amazon rds which is running on 3306 port number. It is getting time out.

@FenilShah - we do not do anything to block access to external ports from one of our hosted properties like codenvy.com or beta.codenvy.com. Are you accessing services that perhaps are behind a firewall? It may be RDS, but there may not be a clean connection from our servers to that endpoint.

@TylerJewell I am trying to check port status on codenvy. But it is blocking with I don't have permission to access iptables. See the attached screenshot.

@FenilShah there's nothing on beta.codenvy.com that blocks or somehow interferes with outbound connections.

Are you sure your database is set up to accept external connections?

[FenilShah]

Yes. I did open it for all IP. I can connect it with my local machine but not able to connect with beta.codenvy.com. It is getting time out.

@FenilShah I have just tested a simple php script that connects to a remote DB over 3306 port. No issues.

Can you connect to your DB from a local machine?

[FenilShah]

Yes, I am able to connect amazon RDS from my local machine, same app is working in my local. Even I also tried to test my app by installing mysql server in codenvy. It works fine but I don't know why it is not able to connect to amazon RDS. Stuck with connectivity.

Perhaps you have to whitelist beta.codenvy.com IP?

[FenilShah]

Let me check. And will get back to you. Thanks.

@FenilShah let me know if you need IP addresses of beta.codenvy.com machine nodes

[FenilShah]

@eivantsov Yes, you were right. It was my RDS blocking this codenvy machine IP. That's ok, it's my just development database server. So I opened for all IPs, now I am able to connect. Thank you so much for your kind support.
