Hi there, I have some linux instances running on AWS but sometimes when we try to connect to the instance its say "Network connection failure" and same when I check on AWS EC2 console its says 1/2 status check failed. and after rebooting the instance sometimes its works perfectly and sometimes it got completely disconnected and after this we have to recover the data from EBS volumes and required to create new instance. But the previous instance was not in work. Please provide me a solution, why it is happening?
Hello everyone, as a complete beginner in AWS, I'm following a coursera course for AWS beginners. One of the first exercises is to create a EC2 instance via the AWS console. They provide us with a little script that boots up on an app on the virtual machine, and should then be accessible with an HTTP call on the public IP. I don't what's exactly going on but it seems that the page is loading forever and then times out when I try to access it on a web browser at the address http://<public-ip-address> Does anyone know what could be going on ? Here are the details of the EC2 instance I've launched : Amazon Linux AMI t2.micro HTTP protocol (source: everywhere) I've configured a key pair default VPC chose first subnet ![subnet](/media/postImages/original/IMf2NUIq3bRGaWDyihOOMz1A) ![subnetmapping](/media/postImages/original/IMSEVBK6LdS3WwRIvIJeT2yw) I also have an error when trying to use EC2 Instance Connect. (maybe because I have only configured HTTP and not SSH) ``` Failed to connect to your instance EC2 Instance Connect is unable to connect to your instance. Ensure your instance network settings are configured correctly for EC2 Instance Connect. For more information, see Set up EC2 Instance Connect at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-connect-set-up.html. ``` If anyone could help me debug this, that would be really helpful. Thank you for reading me !
We have setup remote apps to be used via RDP on a Windows Server. Users have reported that they will get disconnected mid-session. They are usually logged in all day. We haven't been able to find a cause. We have done the following: 1. Increased the server hardware based on AWS provisioning suggestion 2. Set up Domain and Local GPO to keep instances active, auto reconnect sessions, and only allow one session per user 3. Checked the Remote Desktop App settings to ensure we don't have a timeout issue there 4. Checked Event Logs both on the server and at the AD controller (No errors) 5. Checked security settings for anything potential connected to remote desktop 6. Made sure we have remote desktop licenses installed We are running the Apps over a VPN and each server is setup to serve as a RD broker as well as host the RD App. Any ideas?
Hello, Today I attempted an instance type change on a Windows machine from m5.4xlarge to c6a.4xlarge resulting in Instance reachability check failed. I've tried rebooting, stopping, and starting the instance, but the outcome was the same: no connectivity. Are there any networking differences between the 2 instance types that would require driver installation? I'm asking about the network, as the instance screenshot displayed no connectivity on the network adapter and the remote desktop connection was not working either.
One of our EC2 windows (Windows 2022 Data Center Edition) instance randomly stops without any manual interference. It's a **c6a.8xlarge** instance type running at **Mumbai location**. The server is used for RDP purpose. Whenever users complain they are kicked out of their sessions, we mostly see that it is in "Stopped" mode in the dashboard. This is really impacting our production. How do we resolve this issue?
I created a new Ubuntu 22.02 LTS instance two days ago. Instance type T2.Medium. Every night at about 08:20 UTC I get an error message in the log 'eth0 Could not set route: Connection Timed Out'. up until this point my log is full of standard docker messages about mounts being deactivated and the application is running fine. All normal messages have stopped, docker isn't deactivating various runc.* mounts up until this point. once that eth0 could not set route message appears the runc messages stop after that the instance is unreachable and fails the instance checks, I am unable to stop it gracefully. Once it is force stopped, and restarted then it was fine again, until that time the next day when network connectivity is lost. This has happened two days in a row. There is no indication in the syslog except that eth0 timed out, and fails. I've had machines ssh'd into it and they get disconnected.
Hello, Does the time window for calculating the money spent in the **Savings Plans** always **start at the full hour** (e.g. at 13:00, 14:00, 15:00 etc. and NOT e.g. at 13:05, 14:05, 15:05 etc.)? According to the chart in Cost Explorer (with hourly granularity enabled) this is the case, but I didn't find it explicitly mentioned in the documentation.
Hello Team, For the AMI ID ami-02f3f602d23f1659d (al2023-ami-2023.0.20230315.0-kernel-6.1-x86_64), I am seeing that crontab is missing [root@ip-172-31-11-172 ~]# contab -l -bash: contab: command not found After that I have installed the crontab manually using the command **yum install cronie cronie-anacron** But could you please let me know, Is the AWS missed to include crontab or hereafter the AMI will come up without crontab. Could you please confirm.
I have 2 ec 2 instances running and am able to login to both from pc desktop but not from Android mobile It is my understanding that we can have 2 connections through rdp, is these connections to the server or the instances, so my question is my having 2 instances is that my connections used up and I need to pay for rdp licence then? Or should I be able to connect through my mobile as well? If it is possible to connect through mobile, can someone detail the process for doing so? If I need to buy licences, where do I find details to do that and also associated costs, I would need a connection to each instance through mobile, so is that 2 rdp licenses required? any pointers appreciated Many Thanks Gordon

I'm running a drill on servers that are using the same configuration in DRS. One of the servers fails with the Error: Failed to connect using HTTP channel. The other servers failover as expected. All servers are using the default security group created by DRS. The launch templates are similar, same subnet, etc. How can I troubleshoot the HTTP error?
