socket.io-client-cpp does not connect to node app on Heroku

[akontsevich]

socket.io-client.cpp does not connect to node app on Heroku while Node JS socket.io-client does without any problem. Error is:

[2018-12-11 19:32:43] [connect] Successful connection
[2018-12-11 19:32:43] [error] handle_read_http_response error: websocketpp.transport:7 (End of File)
[2018-12-11 19:32:43] [info] Error getting remote endpoint: system:107 

How to fix? Any workaround?

[akontsevich]

Changed URL from https to http://myapp.heroku.com - works now. Is it possible to connect via https as well. JS socket.io-client allows this.

Built app with SIO_TLS in DEFINES (-DSIO_TLS) - connects via https fine now!

Solution found here: #137

@akontsevich I'm still trying to connect to a simple node js server hosted locally (which is using http) build using express, and implemented a simple socket.io on it. But I'm still stuck in connecting, and getting the following error.

[2019-03-30 19:37:34] [connect] Successful connection
[2019-03-30 19:37:40] [error] Server handshake response error: websocketpp.processor:20 (Invalid HTTP status.)
Connection failed.

I'm trying to run the console example app, and using VS 2017 and 141v toolset. I also pointed the submodules (rapidjson and websocketpp) to their head. Any other change I need to make?

@pampas93 also get following error today trying to connect to local node.js server:

[connect] Successful connection
[2019-09-11 16:22:31] [error] handle_transport_init received error: TLS handshake failed
[2019-09-11 16:22:31] [info] asio async_shutdown error: asio.ssl:336462231 (shutdown while in init)

cause for production I've built with DEFINES += SIO_TLS in .pro file (-DSIO_TLS compiller switch). Commented this out for now for local unsecure run.
