See original GitHub issuespring cloud Finchley.M9 spring boot 2.0.2.RELEASE

routes:
- id: signal_sockjs_route
uri: lb://signal

using
websocket = new WebSocket(arg.url);
//连接发生错误的回调方法
websocket.onerror = function () {
if (!!arg.error) {
arg.error();
} else {
console.log('发生灾难性错误');
}
};
//连接成功建立的回调方法
websocket.onopen = function () {
if (!!arg.open) {
arg.open();
}
};
//接收到消息的回调方法
websocket.onmessage = function (event) {
if (!!arg.message) {
arg.message(event);
}
};
//连接关闭的回调方法
websocket.onclose = function () {
if (!!arg.close) {
arg.close();

@SteveOnorato Thank you very much for your answer! My problem has been solved, different from yours, caused by another reason, but at that time I did not know the reason, I thought it was consistent with your problem.
Ok, I was able to fix my problem by setting the Host header for that route in my RouteLocator Bean.
It looks like the service behind the proxy has a regression where it enforces the Host header for Web Sockets despite my configuration telling it not to do that (and confusingly, that config DOES work for all the paths that are not Web Sockets).
