MATE Desktop won’t open Chromium
I launched an EC2 instance based on the Amazon Linux 2 with .NET 6, PowerShell, Mono, and MATE Desktop Environment AMI on a t3.large instance and successfully accessed the MATE Desktop environment through my RDP client - I got to the desktop, clicked on the button on the lower left hand corner and navigated the menu to open Chromium. I clicked on the Chromium button, but Chromium didn’t launch. I can open other desktop applications in the menu, such as Caja and MATE Font Viewer, but Chromium won’t open. The Applications menu does close after I click on it, just like the other apps, but the other apps open and Chromium doesn’t. Am I doing something wrong?
Private Instance and Public ELB HTTPS Problem.
My VPC structure looks like this: VPC: 1 Public Subnet : 2 (1 Public Instance in each Subnet) Public ELB : 1 (Public ELB for Public Instance above) Public Subnet : 1 (for NAT Gateway) Private Subnet : 1 (1 Private Instance) Here, the Private Instance should connect to the Public ELB. At this time, HTTPS communication should be established between the Private Instance and the Public Instance behind the ELB, but HTTPS communication is not possible because the Public ELB is playing an intermediate role. How can I solve the problem? Or is the structure wrong?
How to calculate the number of hours covered by EC2 Instance Savings Plans
I am using EC2 Saving Plans for 6 instances. In the bill, I see On Demand Linux Instance Hour (hrs) and usage covered by EC2 Instance Savings Plans (hrs). I wonder how I can calculate the usage covered by SP. For instance (on August): - Commitment: $0.42400/hour - $0.125 per On Demand Linux m4.large Instance Hour: 4,464.000 Hrs (= 6 x 24 x 31) - m4.large Linux instance usage in ap-southeast-1 covered by EC2 Instance Savings Plans: **4,393.599 Hrs** - SP rate: $0.07400 - On-Demand rate: $ 0.12500
Is it possible Private EC2 Instance send outbound traffic to Public ELB?
Here is the AWS structure I created. - VPC : 1 - Public Subnet : 2 (1 EC2 Instance in each Subnet) - Public ELB : 1 (About Public Instance) - Private Subnet : 1 (1 EC2 Instance) Here, I want to make a request to the Public ELB from the instance in the Private Subnet. How can I do this? Or did I get the structure wrong?
ASG - Instance purchase options and Allocation strategies missing
I try to create ASG but there is Instance purchase options and Allocation strategies sections missing. It's not there either during create, edit or review. I've some ASG created >1 month ago and it contains Instance purchase options and Allocation strategies sections. However when in this old ASG I try to edit Instance purchase options it goes to editor view with Instance purchase options and Allocation strategies missing. Also when I tried to create ASG similar to the one created >1 month ago it still doesn't have Instance purchase options and Allocation strategies sections. What's going on?
Running Hyperledger Besu instance on EC2
I'm trying to start a node for a private implementation of Besu on my EC2 instance. However, every time I try to start the node, it throws a java.net.ConnectException immediately on start. There is no message given, no cause, just throws the exception immediately and dies. I've checked the security groups, and all the necessary ports are open. I tried it with and without UFW and no success. I also tried using ports that are already standard defined but not commonly used UDP/TCP ports, and that did not work either. It runs successfully in our local dev environment, so I know the difference is environmental and not a code issue, but I'm not sure where else to look. The Java version is the same, the compiled jars are the same, and I've tried everything I can think of with regards to opening ports on the EC2 instance.

BUG on EC2 AMI Catalog page: Clicking in the "Select" button does nothing.
I am facing a bug on [EC2 AMI Catalog page](https://us-east-2.console.aws.amazon.com/ec2/home?region=us-east-2#AMICatalog:). I go to the page, click at the "Select" button but nothing happens, it is unresponsive. I have not been able to create a new EC2 instance for months because of that, which is worrisome. I tried all browsers: Firefox, Chrome, Edge, but the same problem occurs. I recorded a gif to show the BUG: https://media.giphy.com/media/g3Jc3vNwAHRkk1mKPC/giphy.gif If someone knows what is the issue, please, any help will be much appreciated.
EC2 Instance Unreachable After Failed Status Checks
One of our instances reported a failed status check and became unreachable. Tried rebooting and start/stop to no avail. Usually that works. Also tried creating a new instance based on a snapshot and have the same issue. Tried changing instance type from t2 to m4 as well. Any ideas? Thanks.
