AWS Install Bitbucket Server Problems

[luiseffe]

Hello Recently I'm trying to install bitbcuket server 5.2 on AWS 

by doing this: https://confluence.atlassian.com/bitbucketserver042/quick-start-with-bitbucket-server-and-aws-794209761.html

Everything seem's fine but when i'm in the process of creating de AWS, got and error on the stack wich is:

10:25:10 UTC-0500

CREATE_FAILED

AWS::EC2::Instance

BitbucketServer

The requested configuration is currently not supported. Please check the documentation for supported configurations.

To be honest i don't know why, recently recommend me to use AWS because there's where works without any problems and the installation its also good but i'm having thise kind of errors which i don't have idea what could be.

Following this recommendation, i'm doing the firstne E2

https://confluence.atlassian.com/bitbucketserver/recommendations-for-running-bitbucket-in-aws-776640282.html#RecommendationsforrunningBitbucketinAWS-BitbucketServer

Also before this, Tried by installing SSH on the instance and everything, it's running with no errores thats what the log says but the web page dont load. 

So i'm out of ideas, anyone? Please.

Thanks.
