Unable to see the demo of how sse connection is created
As per the details given in documentation, I tried to see the example of SSE in openfire but when I visit http://{{server_name}}:7070/apps/sse/index.html . I am getting a 503 error. And unable to see how the SSE Works. I have attached a screenshot of the issue. Can you Please help me to fix the issue or can you at least provide some information on how can I fix this.

@lokesh-osian wow you can open https://localhost:7070/apps/sse/index.html ? I cant open it. I've got ERR_SSL_PROTOCOL_ERROR like this: sse error
how to open apps/sse/index.html ?
You need to provide basic authenticate headers and already login with the Openfire Chat REST API. Otherwise, there is no data to send you over the SSE connection.
See https://discourse.igniterealtime.org/t/openfire-chat-api/68792/62
I feel like I'm missing something here...
I do a /chat/login just fine to the server, then I try and issue a GET to http://xmpp.mysite.com:7070/rest/api/event/source
and all I get are 404s. I pass basic authorization headers with my username and password and still get nothing.
