While everything is running in AWS dashboard, somehow an error - "looks like your AWS remote server is down, please check your instance in the AWS console and connect again."

Question

Hello, I'm trying to run a web-based app http://fullmontesuite.herokuapp.com/application/tutorial
I went through the whole guide then went to AWS and installed a server.
After installing the server and acquiring the .pem file, the DNS, and the port - it still shows that the server is down.
The instance is running, status checks are done(2/2), security group is aligned perfectly - I really cannot understand where could I go wrong.
I have searched here but nothing is available for my problem in its specifical form somehow, almost every time it was something different.

Thank you very much in advance,
sorry for your precious time,
 hope that this great forum will be as helpfull as the AWS itself.

Answer

Probably, the problem was a DNS caching issue. If your DNS servers assigned from your ISP provider, the cache time will change for every provider but mostly they are using default settings. You can use Google or CloudFlare DNS service or.choose other one which is okay for you.

There is nothing wrong after 6 mins. I see **Copyright © 2021 The FullMonte Project** on footer and your website is working with HTTP 80. port which is unsecure and not recommended. You should use an SSL certificate for your web server application which is nginx or Apache.
