Server ports 80 and/or 443 are not publicly accessible

Question

Please its been 2 weeks now, have tried everything but each time I telnet telnet  443 or telnet telnet  80, I keep getting;  telnet: Unable to connect to remote host: Connection timed out

And when I do curl -I   80, I get curl: (7) Failed to connect to  port 80: Connection timed out.

My  is an elastic IP.

**NOTE: Outside my instance, I noticed I could telnet to port 80 and 443 using my  and it works but when I SSH to my instance and telnet or run curl, it doesn't work.**

Please help

Answer

Check the network access list of the VPC your EC2 instance is located

Answer

On my security group, port 80 and port 443 are open.
Have flushed my iptables, so rules available, no firewalls  .

Please what might be the cause.

When I run curl -I 127.0.0.1 , this works, but when I replace with my IP ADDRESS, it doesn't

Answer

If you are experiencing urgent difficulties I would always recommend that you raise a support case. The support team can look at the configuration of your environment and tell if anything is not configured correctly.

Your question seems a little contradictory but let me try and summarise:

1. You can reach your instance using it's public IP address on TCP/80 and TCP/443 from sources outside AWS.
 2. You cannot reach your instance using it's public IP address on TCP/80 and TCP/443 from the instance itself.

If (1) works from "anywhere" then I'd expect (2) to work as well. Check your security group settings for your instance and make sure you're allowing the appropriate source IP addresses - the default is to allow connections from anywhere so that may not be it.

Second, check the instance firewall/iptables/filtering - it's possible the operating system is blocking connections from specific source (i.e. itself).
