AWS RDS connection from localhost - amazon-web-services

I'm trying to connect to a RDS database (used alongside Elastic Beanstalk) from PGAdmin. From the "Connectivity & security" tab on the db dashboard, I selected the VPC security group and then edited the inbound rules to include a new rule of type "All traffic" with "My Ip" as the source. But adding my ip to the inbound rules does nothing, I keep getting timeout: expired on PGAdmin.
From what I can see on other questions & answers, this seems to be the only required configuration to change, however it does not solve the problem for me.
Does anyone experienced this? What do I need to do to connect to the database from PGAdmin?

Tableau cannot connect to redshift server

Tableau cannot connect to the redshift server.
It displayed:
An error occurred while communicating with Amazon Redshift
Unable to connect to the server. Check that the server is running and that you have access privileges to the requested database.
Error Code: BC42EF73
could not connect to server: Operation timed out
Is the server running on host "redshift-cluster-1.cncrnka9xarv.us-east-2.redshift.amazonaws.com" (3.143.87.206) and accepting TCP/IP connections on port 5439?
I just followed the setup in AWS Redshift Connection with Tableau - YouTube but it fails. What's the reason?
The first thing you should check is the Security Group associated with the Amazon Redshift database, since the video did not reference it.
The Security Group should permit Inbound access from 0.0.0.0/0 on port 5439. Note that this makes your database accessible to anywhere on the Internet, which is not good from a security perspective. However, I couldn't find a reference to the range of IP addresses that Tableau Online uses.
If that doesn't help, then confirm that the Redshift database is in a public subnet. A public subnet is defined as having a Route Table entry pointing to an Internet Gateway.
Solving this error contains 2 steps:
download the AWS redshift ODBC drive from here
Follow what is given in this answer by #JohnRotenstein.
For doing that follow the following steps:
Go to the cluster with which you want to establish the connection.
Then go to "Properties" tab.
Then below there is a section named "Network and security settings" which has "VPC security group" tab and below that there is a link that will redirect you to Security group of the VPC.
Select the VPC and then select the "inbound rules" tab.
There will be a security group where under "source" there will be something starting with "sg-" which means all the connections to redshift from the internet is blocked and only the addressed with this origin will be able to connect with AWS which are EC2 instances.
There click on "Edit Inbound rules".
In the window that opened up, click the "Add rule" button.
Security group rule ID - This you do not need to set
Type - All traffic
Protocol - All
Port range - All
Source - Anywhere Ipv4(not recommended) so it will be set to "0.0.0.0/0".
Description[optional]
Here set the Source to the IPaddress from where the connection request is going to be made and not the above one.
For all other connection queries can be solved by following this link

AWS Neptune Host did not respond in a timely fashion - check the server status and submit again

Ive went through the whole start-up tutorial and connect to the tinkerpop3 server remotely from an EC2 that is in the same VPC and get the error
gremlin> g.addV('person').property(id, '1').property('name', 'marko')
Host did not respond in a timely fashion - check the server status and submit ag ain.
Type ':help' or ':h' for help.
Display stack trace? [yN]
any reason this might be happening?
Let's try a couple of things to get you started with debugging the issue here:
Have you tried hitting the /status endpoint? If this endpoint is working, then there is a problem with the console configuration. If it isn't, then there is an issue with the connectivity of the EC2 instance to the DB.
Can you ensure that the EC2 instance has been launched with the same security group for which you gave inbound access to port 8182 on the DB (during step#8 in the setting up instructions?
Please ensure that your cluster and instance status is "available" as observed from the Neptune console.
The recommended way to manage such connections is 2 have 2 security groups:
client - A security group that you attach to all clients, like Lambdas, EC2 instances etc. The default outbound rule gives you outbound access to every resource in the VPC. You can tighten that if you'd like.
db - A security group that you should attach to your Neptune cluster. In this security group, edit hte inbound rules, and explicitly add a TCP rule that allows inbound connections to your database port (8182 is the default port).
You can attach the db security group to your cluster either during creation or by modifying existing clusters.

Amazon RDS db connects locally but not on production

I was able to connect to the amazon rds aurora database locally, and run queries.
But on production EC2 server, the connection returns 500 server error "SQLSTATE[HY000] [2002] Connection timed out".
I've added the same credentials for the database to production, and can see they are being used in the error log.
I enabled the 'allow public access' setting.
I added all the security groups I have to the database (this is probably the problem, I didnt create any special groups, just whatever amazon suggested I let them do).
How could it be working locally but not on production?
Can you check your production server security group outbound rules. if it is connecting from local and not connecting from production machine , so should be some outbound traffic timeout.
It was a security group issue.
The default rds-setup-wizard security group was applied to my database instance, and this gave me local access. I guess it had my ip address or similar as an inbound rule.
I had to add a new security group and add that new group to the database instance.
My new security group needed an inbound rule that looked like this:
Type: MYSQL/Aurora
Protocol: TCP
Port Range: 3306
Source: my EC2's private ipv4 address with /32. Eg: 13.14.15.16/32

I have followed the guide, disabled my firewall, verified my security group allows access to everything (initially set to public). Still, 2 installs of mysql won't let ssms connect. No idea why this doesn't work

could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "posttest.cnmcgcqc8rkx.us-east-1.rds.amazonaws.com" (52.2.0.231) and accepting TCP/IP connections on port 5432?
mysql can connect, might have to go with that
ecurity groups are not under RDS, they are under EC2's console. ACL's options are under VPC's console. This is not even mentioned in the guide. Seen someone connect on youtube with my exact settings...
This could be one of many things with the given information. The first thing I would check if you know your security groups are set up correctly is to open the port on the Network ACL Inbound Rules.

Why Amazon EC2 is not accessible using ping?

I've been using AWS for a few months without any problem. But from yesterday, I can't access the website. When I ping the IP (52.24.23.108) it displays request time out. Server's status is okay - that I checked from AWS console. Isn't it a network problem of Amazon Webservices?
You need to enable the specified network traffic type (ICMP) through your security groups for your instance. You can do this by choosing Security Groups > select your security group and choose Edit Inbound Rules
Choose "ICMP" from the dropdown and source (* if you want it from everywhere) then Add Rule
PINGs should work!
A couple things could cause this, most likely you provisioned the instance with a public IP, by NOT a n elastic IP. If you had a server restart, either by your doing or by AWS, then your public IP would be dropped. If you did use a elastic IP, then look at your security group to see if you allow icmp still or if the security group changed.
Another cause may be if a server level firewall had been disabled in the past, but if your server went through a restart it may have started again. What base OS are you using?
