为什么在 Azure SignalR 上调用通知时出现连接错误

Question

I have configured a SignalR resource on my Azure account and am sending a message to the SignalR Hub using the below snippet in an Azure Function written in C#:

await signalRMessages.AddAsync(new SignalRMessage()
            {
                Target = "notify",
                Arguments = new object[] { requestBody }
            });

但是，我不断收到以下错误。

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

I have also verified that the Azure function URL for negotiate function returns me the below information as expected.

{"端点":" https://xxxxxxx.service.signalr.net:5001/client/?hub=broadcast ","accessKey":"yyyyyyy"}

为什么会出现连接错误，我可以在配置中进行哪些更改？

此错误意味着没有服务器在您尝试连接的指定 ip/端口进行侦听。 这可能是由于使用了错误的 IP 地址或错误的PORT引起的。
