Re: Websocket Handshake failed

[Srinivas Murthy <the.srinivas.murthy@...>]

In my case the client is lua but the server side is java script.
On a CentOS 7 OS running the Lua client, I dont see the problem
connecting to the Websocket server. However, running on a Ubuntu 1604
OS, running the same Lua client, I see this problem.

Do you have any ideas to fix this?

Thanks
