Describe the bug

I have implemented the @microsoft/signalr@8.0.0 also tried v7.0.12 and v6.0.33 in our project. It's a bidding website so realtime updates are essential part of the project.

Issue: Upto 3- 4 connections it works fine but when 5th connection is attempting to connect it stucks, and if we disconnect one of previous connected user then the 5th connection is connected.

What I have done: I checked the ReactJS and backend (ASP .net core ) code as it is as per the documentation. We have also increased the concurrent limit to 10k.

Below is the code used for connection to hub:

const getUpcomingLots = async () => { setLoading(true); try {

  let hubConnectionBuilder: any = new signalR.HubConnectionBuilder()
    .withUrl(HUBURL, {
      headers: {
        "Cross-Origin-Resource-Policy": "*",
      },
      withCredentials: false,
    })
    .withAutomaticReconnect()
    .build();

  hubConnectionBuilder.start().then(() => {
    hubConnectionBuilder.on("SendUpcomingLots", (data: any) => {
      setUpcomingLots(data);
    });

    axios
      .get(`${APIURL}?auctionId=${ID}&customerId=${customerId}`)
      .then(() => {
        setLoading(false);
      })
      .catch(() => {
        console.log("APIURL Error Send", new Date());
      });
  });

} catch (error) {
  setLoading(false);
  console.error(error);
}

};

Any help is appreciated.

Expected Behavior

Multiple connections should work. Even if 1000 users connects to the hub they all should receive the realtime updates.
