Note that the Windows platform section of our required SDKs FAQ has said for a long time that Websockets will have issues on Win 7:

Certain functionality in the game, like secure websockets support in networking or various elements of security when doing HTTP requests, will prevent the use of Win 7 and Vista (or might at best require your players to install the final Win 7 Service Pack) and we are unable to do anything about this. Similarly, using any third-party extensions may have the ability to restrict this also, so please speak to the asset/extension author if you have any issues with older versions of Windows and your game.

However, the manual does not appear to have anything saying this, so if nothing else that should be documented there also.

this mentions specifically secure websockets, which is probably wss? if that is the case, i would expect the ws connection to not error out like that

If you update it to say that any websocket connection is unsupported, i would be fine with that

I don't have a Windows 7 machine handy to test your project, but WebSocket isn't supported on Windows 7.

If network_create_socket() is called with network_socket_ws or network_socket_wss it will print an error to the console and return -1 (hence the invalid socket index error when you subsequently call network_connect_raw_async()).

then please update your documentation to say that it's any websocket code unsupported, thank you
