Hi Andy,

image

as shown in the image, the websocket client have not close the websocket conenction, but my websocket server going to the callback case LWS_CALLBACK_CLOSED, i don't know why, if i change the websocket client to postman from web client, then i can't reproduce the problem. will the lws going to LWS_CALLBACK_CLOSED because the other side tcp windows buffer is full? what could be the root cause?

There are verbose lws logs that describe what it's doing and why. You should maybe have a look?
