It's the thrid day that i try to use these library
https://github.com/morrissinger/ESP8266-Websocket

but i have trouble with it
I have some issue with the websocket client part. I try with the example and i have the following message on the serial port:

Connecting to NUMERICABLE-A8B3
.........
WiFi connected
IP address:
192.168.0.22
Connection failed.

ctx: cont
sp: 3ffea780 end: 3ffea960 offset: 01b0

I modify the different information and try to connect to my own websocket server and i have the following message:
Connecting to NUMERICABLE-A8B3
...........
WiFi connected
IP address:
192.168.0.22
Connected
Client connected
Sending websocket upgrade headers
Analyzing response headers
Invalid ANALYSE REQUEST
Terminating socket
Handshake failed.

I also test my server with the websocket echo online client and it worked. But with your client it does not work It seems that the client nerver received data from the handshake.

Did somebody have a websocket client that worked?or canhelp me since i didnot see any trouble on the library?
My idea is to build several modulethat push captor information by websocket to the server.And server can also send information to these module.

Sorry for my poor english...

I am stuck with this error since a week now. Any help would be greatly appreciated.

Thanks in advance

That header handshake looks like wss for me. If you want to use WSS (which is highly recommended - espiaccally when you speak websocket with a server on the internet) you may need another library with supports WSS

have a look at Links2004 library
