First thing first, I have checked almost all the answers related to this but couldn't find the cure to the problem.
To connect to RDS, I know that we need to set the inbound rules in the security group associated with the RDS instance to my machine's IP, which is already set.
Am just using a mysql client like sequel pro, specify the RDS endpoint, mention the username and pwd but everytime the connection could not be established.
There is no firewall as I am using my mobile internet by connecting my machine through hotspot.
One important thing that might be causing the issue could be the subnets that are associated with the default VPC on my RDS. I have 2 public subnets and 2 private subnets associated.
Also ran the command nc rds-host port, even that also timed-out.
Tried all troubleshooting steps but still not able to connect. Could somebody throw some light here. Stuck for a very long time.
This is the error:
Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).

I'm trying to debug an ODBC connection failing to a MySQL instance on aws rds. The connection works on all but a single machine. This machine is connected to large financial systems network, so I assume it would be the firewall.
So far, I've..
made rds instance public accessable
whitelisted the machine's IP
had their network folks open port 3306 on machine.
network folks confirmed data is going out port 3306, but nothing is coming back.
traced on machine's odbc log...10060 error (usually inbound rule to RDS error..)
opened ALL inbound to RDS to accept from all (0.0.0.0/0 ) - still get error
setup the RDS instance error log, but doesn't record these failed connects. It seems to only log if it is a user/password fail..?
my questions:
is there an aws rds log that would show these failed attempts?
does windows firewall on port 3306 also need an inbound rule? Or does opening it assume inbound/outbound?
Again - all the other machines are able to access the rds mysql fine. Only this one can not connect - and i am sure it's very protected, due to its access to major financial systems.
any ideas what else I can try?
thanks!
On your security group you will need to enable for public access (or just your IP), and sometimes it can take a long time to apply these changes, for me it took 5 hours once upon ago;
So I believe the issue is that on firewall setup, they are allowing incoming on 3306 only if its a secured connection (using ipSec I believe).
i'll likely need to look into a vpn to connect to AWS rds.
I have an RDS instance that I was able to connect to remotely fine for months now. However, tonight I downsized the DB because we we're paying for a lot of unused CPU. After the change from m3.medium to the t2.small I can't connect to it anymore. I have terminal shortcuts setup so I can't be typoing it. I double checked the security groups and thats still applied and the host is the same and everything. I'm not sure what else to try. I just get:
ERROR 2003 (HY000): Can't connect to MySQL server on '<my-host>.us-east-1.rds.amazonaws.com' (60)
I encountered the same problem today. After upsizing the RDS instance, I am unable to connect to it using SSMS which I was able to do just a few hours earlier. It has suddenly stopped working on two PCs so I could not have accidentally changed some parameters. However the web server accessing the RDS within the VPC works fine
sorry for silly question: are you sure my-host didn't change after resizing? Given the error message, it's not credentials. So, it is either address, or security groups, or VPC-based networking.
I keep running into this error while connecting to my newly built RDS MySQL instance
ERROR 2003 (HY000): Can't connect to MySQL server on
'****.ap-southeast-1.rds.amazonaws.com' (60)
I wouldn't say I am an expert, as I have several EC2 instances running and able to connect.
And I have all the security groups created and necessary permissions for inbound added accordingly. But i just quite connect to the RDS instance.
1. I have re-recreated with guide from AWS document, created new VPC group and dedicated DB security group.
2. Gone through most of the responses from similar questions, and applied the suggested resolutions (which is adding own public IP in the inbound rules) etc..
Any help?
1)
Make sure that the server is running
telnet ****.ap-southeast-1.rds.amazonaws.com 3306
2) Make sure that the server is not bind to specific address.
bind-address = 127.0.0.1
3) Make sure that the IP address that you have added to security group is correct. Don't forget the /32 for a single ip. You can get IP address from
/sbin/ifconfig
4) Make sure that there are no firewalls on outbound traffic on the host from which you are trying to connect
Does your RDS configured as publicly accessible? If not, you can only connect it within your VPC.
Thanks everybody. I was able to resolve the problem. The supported platform uses the EC2,VPC, so my AWS account is in the current region that does not use a default VPC. I dumped everything out, created VPC using wizard, then the security group. Then re-created the DB instance, assigned it the new VPC i re-created. Thanks for your efforts.
I'm trying to connect MySQL Workbench to an Amazon EC2 (Linux) instance that hosts a MySQL Database. (Not RDS but localhost). However for some reason, I can't get it to connect remotely.
Things Ive done:
- Set the security group to allow any IP to access port 3306
- Created a mysql user and granted all privledges on it.
- Modified the my.cnf to include bind-address=0.0.0.0 However i still cant connect.
On this instance I do have SSL cert installed and I am forwarded all http request to https?.. But im not sure if this has anything to do with it.
If anyone could guide my in the righ direction I would appreciate it.
I would personally give it an Elastic IP so it will have a public IP, then bind the mysql to that IP. Make sure the iptables are set to accept the mysql connections. I also wouldnt suggest leaving mysql open to every ip unless this is an absolute necessity.
I'm trying to connect to MySql on Amazon RDS from my computer, using MySql WorkBench, or HeidiSql or even the console Mysql.exe and i'm getting this error all the time:
ERROR 2003 (HY000): Can't connect to MySQL server on 'MY-SERVER-NAME' (10060)
In the Security group of the instance I created a new Inbound rule that allows all traffic, and applied it, and still - same error.
I have no active Firewall on my computer, and have good internet access
I am able to access the DB from the Amazon EC3 server, there I am connecting using HeidiSql, and the exact same settings (host, username, password) is just not working on my computer
Still, nothing is working. I'm pretty sure that my security groups is configured to allow outside connections, as can be seen on the next screenshot, there is another place with firewall rules?
I was having the same problem when using an RDS instance on a VPC that I wanted to connect to remotely. To fix the problem, I needed to do the following:
Go to the VPC Management Console in AWS
Go to Internet Gateways (on the left side)
Create and attach an internet gateway to my VPC. Make note of the ID of this gateway.
Go to Route Tables
Edit the route table associated with the subnets associated with your RDS instance
Add a route:
Destination: 0.0.0.0/0
Target: ID of your Internet Gateway
I didn't have this route in my table because I created my VPC manually and without using the wizard, but if you use the wizard it creates this route for you automatically.
Note: This assumes that your security groups are already configured to allow your IP to connect.
The 2003 error is the Access-Denied Error I would be willing to bet that you haven't configured the RDS to accept your IP address.
This can be done by going to DB Security Groups -> Click Default -> and add a new CIDR/IP range. I believe that if you set it to 0.0.0.0/0 it will accept all ip addresses
I use SQLyog for connecting to Amazon RDS from my machine.

The security group settings are just firewall rules. If you can telnet on your configured MySQL port from the host you are having problems then you don't have the security group issue.
Chances are the MySQL grants are not allowing outside IPs. If you know the root user/password and you can use it to connect from your EC2 instance that works, make sure the user you are using to connect from outside has the right privileges. Here is the doc on how to add a new privilege or create a new user:

http://dev.mysql.com/doc/refman/5.1/en/adding-users.html
http://dev.mysql.com/doc/refman/5.0/en/access-denied.html
Did you assign the security group to your RDS instance? If you didn't modify the default security group, then you need to add your security group to your RDS instance.
In my case, my company had two different network connections. When I went to google and searched "What is my IP?" I got one answer; 209.x.y.z. When I went to checkip.amazonaws.com I got another answer; 199.a.b.c.
I had already added VPC Security Group Rules for 209.x.y.z and it turned out I needed them for 199.a.b.c.
Adding rules for 199.a.b.c fixed the issue.
I had same problem as you, all firewall have been opened, but still can not access to my RDS mysql remotely from my local machine. my finally workout is there is a "Public Accessibility" option on your RDS database. default is "No", after I tick it to "YES", everything is running smoothly now.
