Problem description
Application implements Spring webflux websocket Netty server that forwards ffmpeg stream output to websocket protocol. This application allows multiple viewers to see the stream from their web browser by using jsmpeg javascript library.
This solution works as expected in Firefox web browser.
https://i.stack.imgur.com/X4Fm4.png
But in Chrome web browser the stream fails no load. Chrome browser cannot get data from the websocket connection.
Follows an screenshot of the problem seen in Chrome DevTools.
https://i.stack.imgur.com/xWvll.png
Question
What should be changed in this solution so that stream can be opened in Chrome?
How to reproduce the problem
Pull following git repository: https://github.com/haraldsegliens/spring-webflux-websocket-jsmpeg-chrome-problem/tree/master
Install FFMpeg: https://ffmpeg.org/download.html
Update ffmpeg-command variable in src/main/resources/application.yaml so it references the ffmpeg program in your system
Run Spring application. The application by default creates a following endpoint: ws://localhost:8080/stream
Open view_stream.html in Chrome browser
My research of the problem
Turned on TRACE logs and opened the stream in Chrome browser. I see following error in application logs:

My assumption is that Chrome doesn't "like" something about the given response from the Spring application and then Google closed the connection.
Next what I'll try is to use Jetty or Undertow as server but if it solves my problem, it won't solve my question - why doesn't it work with Netty.
Fixed the problem. Problem was that some web browsers are "allergic" to subprotocol header being empty.
chrome empty subprotocol header network log
There are two possible solutions for this problem.
First solution, fill the subprotocol value. Done the fix in https://github.com/haraldsegliens/spring-webflux-websocket-jsmpeg-chrome-problem/tree/solution/use-protocol and Chrome now handles the stream correctly.
chrome now works by using subprotocol
Second solution, fix jsmpeg so that it doesn't write subprotocol header with empty value instead it should skip subprotocol header. Done fix in https://github.com/haraldsegliens/spring-webflux-websocket-jsmpeg-chrome-problem/tree/solution/fix-in-jsmpeg
Following pull request that fixes the problem in jsmpeg repository: https://github.com/phoboslab/jsmpeg/pull/143
chrome now works by fixing jsmpeg

We have two Spring boot applications using the same Elasticsearch database. The queries work fine. But the console of the second spring boot application is always flooded with these warning messages as soon as it boots up. Is there any configuration we are missing, either in the Spring boot app or at Elasticsearch?
