@daofx123 I have tested your demo config and was able to run the demo.

I have tested with FreeRTOS 202212.01 as well. Though the TCP connection is succeeding, the TLS handshake was failing, hence used the version that has MbedTLS 3.5.1. ---

Just to confirm that it is not something IP4 specific, can you run the following - ```auto Test-Connection -targetname -tcpport 8883 -Detailed -ipv4 ``` Do you have the Wireshark capture for the TCP demo? Also, does the Wireshark capture for the MQTT demo still the same (i.e. no SYNACK)? ---

Okay, thank you very much for the help you’ve provided. I will test using the version of FreeRTOS you mentioned. ---

The Wireshark capture for the MQTT demo is still same. ---

I have rerun the demo in the version you mentioned, but the same issue persists. I’d like to know if there are any other settings you’ve made, or could it be a problem with the Windows version? I am running this demo on a Windows 11 system without a actual physical device, are there any additional settings that need to be configured? ---

Sorry, I misunderstood your question. When I run the command, the output is as follow. ```auto Target: a2vtd9m5hzbrcl-ats.iot.us-west-2.amazonaws.com Id Source Address Port Latency Connected Status (ms) -- ------ ------- ---- ------- --------- ------ 1 FISH 50.112.218.33 8883 182 True Success ``` And the TCP demo I don’t know how to set to confirm if my area able to reach any server. Do you have some suggestions? ---

@daofx123 Im running it on Windows 10. Built the demo on Microsoft Visual Studio Community 2022 (64-bit) - Version 17.9.5. > I am running this demo on a Windows 11 system without a actual physical device, are there any additional settings that need to be configured? Other than installing winpcap and having a wired internet connection to the PC, no other changes have been made. ---

Thank you very much, I have resolved this issue. The reason was simply that there were some problems with the network I was connected to; after rerouting through the router, the connection was successful. ---
