Hi, I'm Zaryab. TLS completing but the connection dropping right after usually points to something past the handshake, not the handshake itself. Common causes on NNF: - Client certificate chain not being sent or not trusted by the NSE gateway - Certificate not issued to the exact member ID or not yet mapped on the exchange side - Gateway router parameters in the config file not matching what NSE provisioned - Source IP not whitelisted for the test market - Message framing or the first packet being rejected, which closes the socket without a response I would need to see your NNF config, the client certificate setup, and a Wireshark or packet capture of the attempted login to pinpoint it. Quick questions: 1. Are you using NSE provided certificates or your own? 2. Which NNF version and gateway router build are you on? 3. Can you share a packet capture of the failed login attempt? 4. Is the source IP whitelisted for the CM/FO test environment? If your setup is already close, this could be a config fix rather than a rebuild. I would rather confirm the cause before quoting hours. Best, Zaryab

Hi there, I’d love to help make this project a great success for you. I understand the issue: your C# NNF/CTCL application completes the TLS handshake successfully, but the NSE Gateway Router closes the connection immediately after the login request without returning a response. I would troubleshoot this systematically by checking: - NNF/CTCL login packet structure and field ordering - Message length, transaction code, sequence number, and header values - User ID / trader ID / branch ID configuration - CM vs FO environment-specific parameters - IP and session registration requirements - TLS/certificate configuration - Byte order, padding, and binary serialization in C# - Login request checksum / message format where applicable - Gateway-side disconnect timing and socket traces - Comparison against the NSE certification/test specification I’d also capture the raw outbound login packet and compare it byte-for-byte against the expected NNF protocol format rather than treating this as a generic socket issue. If you can provide the login-packet code, packet dump

Hi — Team Humaki reviewed "NSE NNF Connectivity Troubleshooting". We read the brief: NNF (CTCL) application in C#. Our Gateway Router login on the CM/FO test market is being rejected the TLS handshake completes, but the connection is closed immediately without any response. Looking for someone with hands Plan: (1) confirm target flows and acceptance criteria plus any repo/credentials; (2) implement the core path you can verify; (3) hand off so you can run it without us. No calls needed. Fixed 3851.34 INR, ~3 days. — Team Humaki (@humakiai)
