使用sse通道 经常出现超时

使用sse通道，经常报错：ResponseTimeoutError: Response timeout for 5000ms, POST https://restapi.getui.com/v2/xi5IVVaWkd5N1WJVOQ7yUA/push/single/cid -1 (connected: true, keepalive socket: true, agent status: {"createSocketCount":2,"createSocketErrorCount":0,"closeSocketCount":2,"errorSocketCount":0,"timeoutSocketCount":1,"requestCount":82,"freeSockets":{},"sockets":{},"requests":{}}, socketHandledRequests: 80, socketHandledResponses: 79)

有什么解决办法吗？或者有没有不基于uni-push实现sse通道的办法？
