[Jagadish-Bommisetty]

Briefly summarize your issue:

i have compiled the smart screen sdk with -DDISABLE_WEBSOCKET_SSL=OFF and imported the certificates into browser successsfully. i loaded the html and i have played song from mobile alexaapp, seen that handshake was cancled and websocket:ErrorLog prints. inde.html was not showing any player info card. i have attached the logs and screen shot of wireshark log. is there any debug level to get more logs in websocetpp..? how to resolve the handshake cancled error.

What is the expected behavior?

index.html need to player info card

What behavior are you observing?

I noticed there are some errors associated to VisualCharacteristic properties in your log.
Is it possible to run the Sample App as such:

./modules/Alexa/SampleApp/src/SampleApp -C <your device SDK config> -C <SS SDK config found here> -L DEBUG9

Thanks for quick response....!
shared logs are with the above mentioned command only and issue was seen in my platform. i have not loaded the page completely in browser. when song starts playing then, i loaded the page.

1. may i know how to get more logs from websocketpp means any flag which enables more logs
2. is this issue with certificates importing.
3. from wireshark screenshot, is this issue from server side or client side.

1. If you are running in DEBUG9 it will show the full log. Also you can build the SmartScreen SDK with -DACSDK_EMIT_SENSITIVE_LOGS=ON flag on should give more detailed logs - this will be very noisy.
2. It could be possible it's a certification issue. Is it possible to run with -DDISABLE_WEBSOCKET_SSL=ON (Just make sure to run in DEBUG mode with -DCMAKE_BUILD_TYPE=DEBUG) just to test if it is working first.
3. Sorry the wireshark doesn't really give us much information.

Thanks.

Thanks for info..!
we can see in wireshark it is communicating with TLSv1.3. i am newbie to this SSL/TLS. what is the default TLS version used by this websocketpp server. will it support for TLSv1.3. if not how to configure server for specific TLS version.

Hello @Jagadish-Bommisetty - The SDK does support TLSv1.3 which is the default. Please let me know if you have additional questions
