Elastic Beanstalk with Flask: Command failing on EC2 Instance

Question

Hi,
what is the best way to see an error log or what exactly is failing on the ec2 instance automatically created with my EB environment? I have successfully found the ec2 instance in my console and was wondering if I could see what exactly was wrong with it.

I have the following error:
`Unsuccessful command execution on instance id(s) 'i-xxxxxxxxxxx'. Aborting the operation. 
`

so I assume that the best course of action is to try and see what's happening on my instance
Does anyone have any tips or potential reasons the flask env would do this?

Hello there!
I have noticed that you would like to know how to review logs from your Elastic Beanstalk instance. 
You may refer to the Elastic Beanstalk logs to help you troubleshoot your issue further and find the cause of the issue at large.

You may follow the following steps to retrieve the full logs[1]:
* 1. Open the Elastic Beanstalk console, and in the Regions list, select your AWS Region. 
* 2. In the navigation pane, choose Environments, and then choose the name of your environment from the list. 
* 3. In the navigation pane, choose Logs. 
* 4. Choose Request Logs, and then choose Full Logs.

If you continue to face challenges with deploying your application and troubleshooting on Elastic Beanstalk you may reach out to AWS PS to help further troubleshoot your issue [2].

Hello everybody, additional way,  you can connect to instance ec2 with SSH client, "1. Open an SSH client.
2. Locate your private key file. The key used to launch this instance is ....  3. Run this command, if necessary, to ensure your key is not publicly viewable." I use mobaxterm for connection, when you connect, type: sudo tail -f /var/log/nginx/error.log
