Describe the bug
Getting an error on connection, xhr poll error both with polling and websocket transports on Android with React Native. cURL and iOS both work without problems. For reference:
curl http://localhost:7777/socket.io/\?EIO\=4\&transport\=polling\&t\=OGBFaH0 0
I tried to log the underlying xhr error from polling.js and got the following log:
xhr poll error 0 , "_incrementalEvents": false, "_lowerCaseResponseHeaders": <>, "_method": "GET", "_perfKey": "network_XMLHttpRequest_http://localhost:7777/socket.io/?EIO=4&transport=polling&t=OGBFaH0", "_performanceLogger": , "_pointExtras": <>, "_points": , "_timespans": >, "_requestId": null, "_response": "Failed to connect to localhost/127.0.0.1:7777", "_responseType": "", "_sent": true, "_subscriptions": [], "_timedOut": false, "_trackingName": "unknown", "_url": "http://localhost:7777/socket.io/?EIO=4&transport=polling&t=OGBFaH0", "readyState": 4, "responseHeaders": undefined, "status": 0, "timeout": 0, "upload": <>, "withCredentials": false> To Reproduce
«@nestjs/platform-socket.io»: «^9.1.6» which uses «socket.io»: «4.5.3»
import OnGatewayConnection, WebSocketGateway, WebSocketServer, > from '@nestjs/websockets'; import Server, Socket > from 'socket.io'; @WebSocketGateway(7777, cors: origin: '*' >>) export class WebSocketService implements OnGatewayConnection @WebSocketServer() server: Server; async handleConnection(client: Socket) console.log('new client has connected'); > >
Socket.IO client version: 4.5.3
import io > from "socket.io-client"; const socket = io("ws://localhost:7777/", >); socket.on("connect", () => console.log(`connect $socket.id>`); >); socket.on("disconnect", () => console.log("disconnect"); >);
Platform:
- Device: Android Emulator (Pixel 3a API 33)

Receiving Error: xhr poll error socket.io client React

New versions of socket.io requires also cors on server side. socket.io/docs/v4/handling-cors

You can try to set up the client connection to use only websocket transport. By default it is using weboscket and polling.
So your code will become:
const socket = io(ENDPOINT, < transports: ['websocket'] >); answered Oct 5, 2021 at 12:31

у всех кроме тплинк, тадам!
дада, помню в сохо впн маршрутизаторах такое было
но справедливости надо сказать ради
они таки прошивки то выпускают для ремонта этого всего
ну и ещё качество нашей русскоязычной поддержки было отвратительным

завел пользователя указал мак и все пошел ставить телефон)) я даже удивлен что до некоторых дошли такие технологии обычно же ручками
То же самое у меня,циски спа.эндпоинт менеджер перепиленые конфиги и все радости жизни,например собираемая с удаленных участков телефонная книга xml,+ еще то что редко кто использует- тел книга астериска тоже хмл но для мобильных сотрудников.удобно поправил в базе само актуализируется.новый телефон именно ввел мак привязал экстеншн профиль и все. вплоть до стадиальной замены прошивки
