## No Application :'(
|
|
|
|
### Objectives
|
|
|
|
Explain what might be possible reasons for the following issues:
|
|
|
|
1. Getting "time out" when trying to reach an application running on EC2 instance
|
|
2. Getting "connection refused" error
|
|
|
|
### Solution
|
|
|
|
1. 'Time out' Can be due to one of the following:
|
|
|
|
* Security group doesn't allow access
|
|
* No host (yes, I know. Not the first thing to check and yet...)
|
|
* Operating system firewall blocking traffic
|
|
|
|
2. 'Connection refused' can happen due to one of the following:
|
|
|
|
* Application didn't launch properly or has some issue (doesn't listens on the designated port)
|
|
* Firewall replied with a reject instead of dropping the packets
