I have an asp.net core app that uses SignalR to report metrics that are visualized in the browser. It has been working fine for several weeks, but today I noticed that SignalR fails to connect very often and even when it connects, it dis...
When a user attempts to navigate away from a page with an active SignalR connection, the SignalR client will then make a best-effort attempt to notify the server that the client connection will be stopped. If the SignalR client's best-effort attempt fails to reach the server, the server...

the connection ID is not present on the server, or there is a proxy blocking WebSockets. If you have multiple servers check that sticky sessions are enabled. [2023-08-08T11:16:10.602Z] Debug: Selecting transport 'ServerSentEvents'. [2023-08-08T11:16:10.602Z] Debug: Sending negotiation re...
大体意思ConnectonId是服务端使用,客户端不应该使用这种不可控的方式进行通信。 可以采用Group或者User这种可控方式通信,并且也有例子给出。 这里插一句,在使用.Net Framwork版本时候,我们网站是使用ConnectionId进行通信,经常出现重连导致ConnectionId变掉,进而通信失败。
