My AWS account nr: 553228681532 I use AWS as a host for like 2-3 months. Previously my website - https://www.chessez.com was working, but yesterday it suddenly stopped working (there's no connection).  Above screenshot shows my conversation with AWS support saying that instances are running and for more-in detail investigation I need to contact technical person. So please, can someone provide a sulotion? What may be causing the issue? ---> Update (message from my developer) i have run some tests on my local environment.. Even if backend is not running frontend should be working atleast. if you get to server support. please ask them to check server logs. apache should be running for backend and npm for angular. tell them not even http://3.69.254.55/html/index.html is working. /var/www is the root pathlg...

Hello Guys, We are working on architecture for web application. We currently have three servers in our design - web server ( front end), application server ( backend) and database - all hosted on Amazon EC2. However, we thought of leveraging Amazon light Sail instead of EC2. Our proposed web application will angular based and going to have dynamic reports with option to steam live video with approximately 10k users accessing the video streaming. Please advise if Amazon light Sail will be suitable for this kind of operations or need to go with EC2?lg...

I am very much confused in terms of how saving plan going to be adjusted between those instances? As an example, if we purchased 4 instances, each instance would cost **$5** per hour and a saving plan would cost **$4**, so we purchased a **compute saving plan** by committing **$13** per hour How this saving plan will be adjusted between those instances? Since 3 instances would consume **$12** how **$1** going to be adjusted? because we have purchased Rs.13 per hour saving plan?lg...

Was trying to upgrade to the latest r6 instances from r5s and ran into an issue with installing numpy in our bootstrap script via pip. Found[ this post](https://repost.aws/questions/QUdF4dL0k9RTeAZaUFiPDJCw/emr-bootstrap-script-with-pip-numpy-installation-fails-on-r-6-instances) that is related to my issue.

Hi, I am trying to launch ManagedNodeGroup with Ubuntu amiFamily. but due to some reason it is failing to create managedNodeGroup. Below is my config ``` managedNodeGroups: - name: serv-test-1 amiFamily: Ubuntu2004 instanceType: m5.xlarge desiredCapacity: 1 volumeType: gp2 volumeSize: 50 privateNetworking: true subnets: - hscn-private2-subnet ssh: allow: true labels: role: serv ``` Just to add that I have created self-managed node group and it is joining my cluster successfully. The thing is I am working behind the proxy and I want to add UserData through overridebootstrap command. but whenever I add the overrideBootstrap flag it says "you must specify custom ami", and when I add custom ami then it says "can't specify amiFamily flag with custom ami" But in order to create ubuntu managed node instance it is necessary to specify amiFamily otherwise it will create AmazonLinux instance.lg...

I have a function that uses `putLogEvents()` method and it works fine locally but not when we push it out to our server (EC2 instance). We are always getting 504. I checked our LB and its allowing all traffic. I am running out of ideas why it is timing out on our server.lg...

Hi, We have just created a brand new account in Amazon EC2. We have also created a default MS-SQL Server database along with a new EC2 machine. However, when we try to connect to this database via SQL Server Management Studio installed on my local laptop, we are running into errors. These errors are not unique. These are typical errors which come while trying to configure connectivity between Management studio and remote database. We have followed all articles and other information available both at Microsoft Technet as well as AWS, however the error have remained unchanged. Details of the error are given below. I would greatly appreciate it if someone have a look and answer them ASAP. Many many Thanks, Manoj Kumar Error Message 1 - Cannot connect to vibexchange.c3uqqhmm412p.ap-south-1.rds.amazonaws.com.

The number of Dedicated hosts you've requested (1) would bring your total up to 1 for the specified group of instance types (mac1). This exceeds your current limit of 0. If you've recently released Dedicated hosts, it may take some time for them to stop counting towards your limit. Try allocating your hosts again after a few minutes.
