| 263 | 263 | The path to the solution: On my instance in eu-west-2a, I ran aws --debug ec2 describe-tags (you may need to do aws configure first). This is much akin to verbose mode of other unix commands. I noticed it hang on a request to ec2.eu-west-2.amazonaws.com. If you do `dig -t any ec2.eu-west-2.amazonaws.com` you see 3 ip addresses, which — as you will see later — are IPs in each of the eu-west-2 availability zones. When I ran curl -v ec2.eu-west-2.amazonaws.com (the v flag is verbose), one of the IPs from dig was used (namely the one in eu-west-2a, where the instance resides) and it hangs. I then went to endpoints for the VPC and noticed a service for the service `com.amazonaws.eu-west-2.ec2`. It had the default security group, which turned out to only allow inbound rules from the default or Java Application with Reverse Proxy target group. |
| 264 | 264 | - Problem: A load balancer's target group health checks fail. I was told the checks failed with 403 errors. |
| 265 | 265 | Solution: This was occurring because the website didn't have any content in the /var/www/html. Whilst a site was still served (namely the Apache test page) it does throw a 403 error. If you fill the directory with and index.html the test then passes and a 200 code is returned |
| 266 | -- Problem: Target platform reload in Eclipse. Sometimes reloading via Window -> Plug-in Development -> Target Platform doesn't work, so open the target definition itself and try reloading there. Often a restart proves helpful after the reload. In addition, you can clean all projects and rebuild; then rebuild the individual projects that fail. Sometimes the errors are actually just warnings and you can try to run the GWT SDM (remember the other SDM's must be run if everything is brand new). Lastly, try clearing the plugins content found at `WORKSPACE_HOME/.metadata/.plugins/org.eclipse.pde.core/.bundle_pool/plugins`. |
