Provisioned EC2 Instances not reachable #355

Closed onlinejudge95 closed 1 year ago

onlinejudge95 commented 1 year ago

Description

My EC2 instance created via this module is up and status checks have passed when checked through the EC2 console but unable to connect to them via putty and/or EC2 Instance Connect.

⚠️ Note

Before you submit an issue, please perform the following first:

  1. Remove the local .terraform directory (! ONLY if state is stored remotely, which hopefully you are following that best practice!): rm -rf .terraform/
  2. Re-initialize the project root to pull down modules: terraform init
  3. Re-attempt your terraform plan or apply and check if the issue still persists

## Expected behavior
Expected the launched EC2 VM to be ready to connect via either PuTTY and/or EC2 Instance Connect.

## Actual behavior
Unable to connect to the instance but the instance is up and running as checked from EC2 Console.

I fixed it by updating my security group, For some reason I had misspelled /0 with /32
