I am currently working on integrating TALQ protocol for smart city communication between CMS (Central Management System) and Gateway. While testing with the TALQ Certification Tool (TCT), I encountered a problem with the Pass-through Test.
Issue Description: GET requests from CMS to Gateway are successfully sent (visible in TCT). Response from the Gateway never reaches CMS – I receive a "Network Unreachable / SocketException" error. Directly testing CMS and Gateway APIs using curl works fine (both respond properly when queried from my machine). Firewall rules are configured to allow inbound traffic on required ports (2000 for Gateway, 3000 for CMS).
What I've Checked: Verified that both CMS and Gateway are listening on the correct ports (netstat shows them as LISTENING). Disabled the firewall completely to rule out blocking issues (netsh advfirewall set allprofiles state off). Confirmed that both services respond to local and remote curl requests. Checked if TCT is correctly configured with Target Gateway Uri and Target CMS Uri set to http://192.168.103.23:2000 and http://192.168.103.23:3000
