ArduinoWebsockets on ESP8266 - Connection closed with code 1006

[sgodey]

I have a Node.js based WSS server that is working fine accepting connections from a linux application. I am using the same Certificate and Keys in ArduinoWebsockets to connect to the same WSS server from a ESP8266. I am seeing a 'ConnectionClosed' event with a reason 1006 (Abnormal Closure). Any thoughts on what is happening here?

Is there an option to spit debug messages in ArduinoWebsockets library? I added

#define DEBUG_WEBSOCKETS(...) Serial.printf( VA_ARGS )

in ArduinoWebsockets.h based on some recommendation ... but does not seem to work. Any help is greatly appreciated.

Below is my Arduino code:

// Before connecting, set the ssl certificates and key of the server
X509List cert(ca_cert);
wssclient.setTrustAnchors(&cert);

X509List *serverCertList = new X509List(client_cert);
PrivateKey *serverPrivKey = new PrivateKey(client_private_key);
wssclient.setClientECCert(serverCertList, serverPrivKey);

// Connect to server
bool connected = wssclient.connect(host, port, "/");

if (connected) {

Hi,

Logs are something that I always wanted to had but never got to it. Also, because I'm not working actively on the library anymore it's up to the community to add that. All contributions are of course welcomed.

I think you saw the macro DEBUG_WEBSOCKETS being referenced for another websockets library, not mine :P

I recommend you go into the sourced and add some Serial.printlns in key locations. Some that I think are good:

• Here to see if the error code is being sent from the server or is it sent by the client (the library)
• This is the only location I found where CloseReason_AbnormalClosure is sent. Have a look at it and add a log there.

Also, make sure in your code that you are calling client.poll.

Hey,

are there any news or workarounds on this Problem?
Not shure if it's the same Issue but I get the same CloseReason AbnormalClosure (1006).

I have a WS Server sending a message in an intervall between 1 ms and 30 ms and want to receive them with a ESP32. For this I use mainly the Example Code "Esp32-Client". If i use a poll the WS Connection Stops after receiving the first Message.
If I use the client.readBlocking(); in an Interval between 30 ms an 200 ms the Connection is Stable. With a shorter Intervall the Connection gets closed with the CloseReason: AbnormalClosure (1006). With a wider Interval than 200 ms the Connection holds up for a few Seconds an then gets closed with the Same reason.
I get the same issue if I check for client.available() befor the client.pull() or client.readBlocking() call.
My guess is that the error occurs when I call readBlocking(), but no new message was sent from the server.
Can I somehow check if there is a new message?

Finally i found the solution the problem not from web-socket package its from WIFI when it's DHCP the ESP8266WiFi.h Package is refresh every 50 sec, when the wifi make refresh the websocket close

so i make the wifi static connection
using

IPAddress local_IP(192, 168, 100, 115);

// Set your Gateway IP address
IPAddress gateway(192, 168, 100, 1);
IPAddress subnet(255, 255, 255, 0);
IPAddress primaryDNS(8, 8, 8, 8); //optional
IPAddress secondaryDNS(8, 8, 4, 4); //optional

and in setup
if (!WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) {
Serial.println("STA Failed to configure");
}
WiFi.begin(ssid, password);

this keep the connection stable

i hope this help how have same problem
