I cannot provide our own code of course. It is part of a big private project.
But I found a similar code on Github that is doing the same problem:
https://github.com/aliakh/demo-spring-sse
Run the code in "demo-spring-5" with:
>gradle clean bootRun

And go to http://localhost:8080/sse/finite/12

You will see that messages are received but nothing appear in the EventStream Tab for the "12" network connection.

I also found a demo that IS working fine:
https://gist.github.com/jareware/aae9748a1873ef8a91e5
Just follow the instruction to run it.
With this demo, we are seing the messages in the EventStream tab.

There is a lot of differences in the request and response headers. In our project, we already tried to mimic the headers from the working example, but still no success.

Thanks for filling the issue...

We have downloaded the .zip file by using github URL ""https://github.com/aliakh/demo-spring-sse"" given in the comment #8 and as we didn't seen any test file in the extracted .zip file.

@Reporter: We are unable to reproduce this issue from TE end. Could you please share a sample URL/test file which helps us in triaging the issue in a better way. 

Thanks.!

????
Goto https://github.com/aliakh/demo-spring-sse
Download the zip file. Extract.
>cd demo-spring-sse-master/demo-spring5-sse/
>./gradlew clean bootRun

When it is running, open Chrome and the Devtool, go to http://localhost:8080/sse/finite/12 with Chrome
