Environment Suddenly Stops working(timeout)

Question

I have a django project hosted on my elastic beanstalk and it is working perfectly before but since the past few days all the instances wont just suddenly response and it will be returning timeout even when the traffic are not much and this on the env message Process default has been unhealthy for 3 minutes (Target.Timeout). we have check the instance for our project log maybe there is a technical issue on the website but no it is working fined and the environment may later work if i 
Restart the app server 
Reboot the instance
Remove our domain from redirecting and later create the record again.
We have even increase our instance type from t3.small to t3.2xlarge it will work but later return the same issue by not responsding to requests and it will be returing timeout.
Please if you can be of any help we would be happy.
if you need any more details too we will provide

Based on your description, it sounds like your Elastic Beanstalk environment is experiencing intermittent health issues that result in timeouts, despite your attempts to resolve them through various methods.

When an environment's health changes to red and you see timeout errors like "Process default has been unhealthy for 3 minutes (Target.Timeout)", there are several troubleshooting steps you can take:

1. Review recent environment events in the Elastic Beanstalk console. These may contain messages about deployment, load, or configuration issues that could be causing the timeouts.

2. Check the environment change history to identify any recent configuration changes that might have triggered the problem.

3. Pull logs to examine recent log file entries, especially web server logs which contain information about incoming requests and errors. This might reveal if your Django application is experiencing issues that aren't immediately apparent.

4. Connect to an instance and check system resources. Even though you've upgraded to t3.2xlarge, there might be memory leaks or other resource constraints in your application.

5. Consider rolling back to a previous working version of your application if the issues started after a deployment.

If these steps don't resolve the issue, your environment might be in an invalid state. This can happen if resources were modified outside of Elastic Beanstalk (through the console or other services), causing resource drift.

As a more drastic measure, you could consider rebuilding your environment. This would terminate all of its resources and replace them with new ones using the same configuration. This can help restore an environment to a working state when it has become unusable.

If you continue to experience issues, using the AWS Systems Manager tool with predefined Elastic Beanstalk runbooks can provide specific troubleshooting steps and recommendations for your environment.
