Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Hello.
This error occurs when there is a problem with the application or the specs of the EC2 or other server hosting the application, rather than an error on the AWS side.
May I ask you to check the application log once?
Perhaps there is an error output that leads to troubleshooting.

I have checked your website and it returns the following message:

Request Method: GET Status Code: 503 Service Unavailable

The 503 error can be caused by the following problems:

• Temporary error: There is some wrong configuration on the server and the web page cannot be reached through the url
• Security measure: When the server is saturated, and to protect user information, this message is displayed
• Page Maintenance: When the page is under maintenance.

Can you tell me more details about the problem?

• Where you have deployed the application
• What language to use the application
• What server are you working with?
• At some point it showed a different message
• Show server logs
