Healthineer, you doin't need to back to WebSockets 2.0.2 version.
You can do work with 2.0.5 doing few changes.
At the AWSWebSocketClient.cpp, keep this line of code without PORT, like this:
sprintf(canonicalHeaders, "%shost:%s\n", canonicalHeaders,awsDomain);
At the WebSocketsClient.cpp, change this part of code with the lines below:
String transport;
String handshake;
if(!client->isSocketIO || (client->isSocketIO && client->cSessionId.length() > 0)) {
if(client->isSocketIO) {
transport = "&transport=websocket&sid=" + client->cSessionId;
}
handshake = "GET " + client->cUrl + transport + " HTTP/1.1\r\n"
//CHANGED
"Host: " + _host + "\r\n"
///////////////////////////////
"Connection: Upgrade\r\n"
"Upgrade: websocket\r\n"
"Origin: file://\r\n"
"User-Agent: arduino-WebSocket-Client\r\n"
"Sec-WebSocket-Version: 13\r\n"
"Sec-WebSocket-Key: " + client->cKey + "\r\n";
if(client->cProtocol.length() > 0) {
handshake += "Sec-WebSocket-Protocol: " + client->cProtocol + "\r\n";
}
if(client->cExtensions.length() > 0) {
handshake += "Sec-WebSocket-Extensions: " + client->cExtensions + "\r\n";
}
} else {
handshake = "GET " + client->cUrl + "&transport=polling HTTP/1.1\r\n"
"Connection: keep-alive\r\n";
//MOVED from outside ELSE to here
handshake += "Host: " + _host + "\r\n"
"Origin: file://\r\n"
"User-Agent: arduino-WebSocket-Client\r\n";
/////////////////////////////////////////////////////
}
if(client->base64Authorization.length() > 0) {
handshake += "Authorization: Basic " + client->base64Authorization + "\r\n";
}
if(client->plainAuthorization.length() > 0) {
handshake += "Authorization: " + client->plainAuthorization + "\r\n";
}
handshake += "\r\n";
client->tcp->write(handshake.c_str(), handshake.length());
//ADDED a debug line just to see the Header we are sending
DEBUG_WEBSOCKETS("[WS-Client][sendHeader] Header: \n%s\n", handshake.c_str());
#if (WEBSOCKETS_NETWORK_TYPE == NETWORK_ESP8266_ASYNC)

I tried to change the Canonical headers statement to not have the PORT number as well, still same issue.
Is this all due to AWS's change of headers OR is this a library issue ?
If so, could you please guide me how to get around this ?
Thank you.

Maybe the problem is related to the SSL Certificate ? As far as I understood, the Websocket connection is SSL encrypted. However, I did not configure any Certificate for this SSL encryption and I did not find any hint how to configure the Certificate (e.g. with espconn_secure_ca_enable).

It might be a problem with the arduinoWebSockets dependency. Check out #9

Also the host name should be lowercase.
A2BF8DY97CWJ2U.iot.us-west-2.amazonaws.com -> a2bf8dy97cwj2u.iot.us-west-2.amazonaws.com
Regarding the arduinoWebSockets:
A port was added to the Host header.
The same port needs to be added to the header before signing it.
sprintf(canonicalHeaders, "%shost:%s:443\n", canonicalHeaders,awsDomain);Any difference in the header will render the signature invalid...

@rahu2581 can you elaborate on:

sprintf(canonicalHeaders, "%shost:%s:443\n", canonicalHeaders,awsDomain);
Any difference in the header will render the signature invalid...
My setup was working just fine. Am not sure why it stopped working once I used a different IAM user.
Appreciate all your help

See #10.
In my case I got the 403 because the dependency arduinoWebSockets added a port number to their host header which is not included in the signed host header.
If you only have problems with another IAM user my guess would be the permissions of that user though.

I also encountered the 403 Permission Problem with my esp8266 (2.3.0).
For me its only working with the 2.0.2 version of arduinoSockets [https://github.com/Links2004/arduinoWebSockets/releases/tag/2.0.2] without sending the port number in the header:
sprintf(canonicalHeaders, "%shost:%s\n", canonicalHeaders,awsDomain);
I tried also the versions 2.0.3, 2.0.4, 2.0.5 of arduinoWebsockets but didn't succeeded neither with nor without the port number in the header

@vitoralvimb @healthineer I've fixed the lib. Now you can use it with the WebSockets library (version 2.0.5) without modifying it
