Tunneling socket could not be established

  1. When trying to run the desktop version, the error below occurs repeatedly.

1720418125223 main info “sendAnalytics: Error while sending request”,{“code”:“ECONNRESET”,“name”:“Error”,“message”:“tunneling socket could not be established, cause=connect ECONNREFUSED 127.0.0.1:8888”,“stack”:“Error: tunneling socket could not be established, cause=connect ECONNREFUSED 127.0.0.1:8888\n at ClientRequest.onError (/home/keikang/work/sw/Postman2/app/resources/app/node_modules/tunnel-agent/index.js:177:17)\n at Object.onceWrapper (node:events:642:26)\n at ClientRequest.emit (node:events:527:28)\n at ClientRequest.emit (node:domain:475:12)\n at Socket.socketErrorListener (node:_http_client:454:9)\n at Socket.emit (node:events:527:28)\n at Socket.emit (node:domain:475:12)\n at emitErrorNT (node:internal/streams/destroy:157:8)\n at emitErrorCloseNT (node:internal/streams/destroy:122:3)\n at processTicksAndRejections (node:internal/process/task_queues:83:21)”}

  1. The photo below is a log for the relevant information, The same message for pressing the login button.

  1. If you look at the message above, it says connect ECONNREFUSED 127.0.0.1:8888, but I do not use a proxy.

First of all, thank you for your answer.

Unfortunately, my error does not occur when calling the API.

This error occurs when running the desktop app and logging into Postman from the app.

Bye

Thanks for the clarification!
