We are running Umbraco CMS on Windows Platform, when accessing the URL, end users are getting 502 errors randomly, and during that time localhost is also throwing 502.3 error which also recovers after some time and URL again becomes accessible, What could be the possible reason for this? and how we can fix this?
Can you give more information? Like: what version of Umbraco, do you have a proxy? Where is the hosting platform?
yes we are hosting on AWS Beanstalk and umbraco Version is 13 based on Windows Platform and No Proxy
Do you get anything in the logs around the times it happens?

This indicates an unhandled exception, which will only be logged in the windows logs, so you’ll need access to the event viewer on your server.
