I’m quite new to AWS, so I’m still learning stuff as I go.
I work on a project where we have multiple environments.
A while ago, I made some changes where I implemented some logic using ServerSentEvents in an Express.js server.
It was working excellent locally, but once I deployed my code to a test environment, the events were not sent anymore to the client, as they were blocked somehow. It took me a lot of time to find what the issue was, almost gave up to SSE, until finally I stumbled across an answer where that person was saying that there should be a setting enabled in AWS to allow the events to be sent.
Now, we have to launch another instance and I need to enable that setting again. The problem is I don’t remember at all where that setting was and I can’t find anything on the internet about this.
Could anyone show me where to find it in AWS Console? I’m going nuts right now!
