why am i getting API error messages
Also i installed jenkins and trying to open jenkins page ipadress:8080 doesnt open why?

Have you created a security group that opens port 8080 for at least some relevant destination public IP address (say, the one you want to access Jenkins from)? You’d need to do that to get out of the EC2 instance’s VPC.

I’d expect the error messages you’re seeing int he page are just for services that you don’t need, and are harmless.

hey rob,

Thankyou for the reply

You’ll need to make sure, of course, that Jenkins is actually running on 8080. You can try this to make sure:

  • ssh into the instance.
  • see what happens when you do curl http://localhost:8080; that will need to work for the security group to allow you to actually access Jenkins from the public IP address of the instance.

  1. Where are you trying to run ssh from? Say, from CloudShell? From your laptop?
  2. When you say “yes i have opened the ports 8080 http”, how did you do that? What settings did you use?

Hi Rob,

Please check

Where are you trying to log in FROM? This will affect how the security group is configured, which I also need to know from you please. Without knowing what you’re doing, there’s nothing I can check.

It sounds like you have not configured your EC2 instance correctly; either the keys are not set up right, or the security group is not set up correctly. You may want to try one of our AWS courses. The first part of this course might be enough to get you started. Since you’re using the playground, you already have access to this course, so it’s a good way to learn the basics here.
