Ngrok's free tier drops TCP tunnels after 8 hours regardless of traffic, that's almost certainly what you're hitting. The fix has two parts: make the tunnel restart automatically when it expires, and add keepalive settings on both the SQL Server side and the client so idle connections don't go stale in between. I'd run ngrok as a persistent Windows service using NSSM (with restart-on-failure), set the keepalive interval in the ngrok config file, and configure TCP keepalives on the SQL Server connection string and at the OS level. That covers the tunnel dying on you and connections dropping during quiet periods. If you want something more stable long-term, I can also set you up with a static TCP endpoint that doesn't have the session limit, takes about 5 minutes alongside the rest. $30, 2 days. One deliverable: tunnel runs stable with auto-restart and SQL keepalives configured and verified. What OS is the SQL Server box running, Server 2019 or 2022?

Hello! This sounds like a classic case where the TCP tunnel is established correctly, but the connection breaks during SQL Server's TLS negotiation, protocol selection, certificate validation, or packet handling phase. I can troubleshoot the issue live using Wireshark, SQL Server logs, SQL Server Configuration Manager, ngrok diagnostics, and Windows Firewall settings to isolate the exact failure point and implement a reliable fix. Before estimating, could you confirm the SQL Server version, whether Force Encryption is enabled, and if clients are connecting with encryption enabled? I'd love to help get this stable and reproducible across all machines.

@SantiagoDev1

I've debugged this exact failure before. The drop happens because SQL Server's TLS/PRELOGIN handshake conflicts with ngrok's TCP passthrough — the certificate CN doesn't match the ngrok hostname, so the client driver aborts. Local connections bypass certificate validation entirely, which is why those work fine. On the screen-share I'll: Check Configuration Manager → Force Encryption + Certificate binding Read the ERRORLOG for the exact TLS error code at drop time Run a quick Wireshark capture if needed to confirm whether the RST originates from SQL Server or ngrok Apply the fix: typically disabling Force Encryption server-side, setting TrustServerCertificate=True on the connection string, or binding a matching self-signed cert Validate live from SSMS through the ngrok tunnel Deliverables: Working connection confirmed on-call + a one-page root cause write-up you can replicate on other machines. Single session, 1–2 hours max. Ready to start today. What SQL Server version are you on, and is Force Encryption currently Yes or No in Configuration Manager?

I understand you're experiencing an issue where your Microsoft SQL Server connection drops during the TLS handshake when exposed via an ngrok TCP tunnel. Local connections function correctly, indicating the problem lies within the ngrok-to-SQL Server network interface. My expertise in network traffic analysis, including ngrok inspection and Wireshark captures, along with deep knowledge of Windows SQL Server configuration and protocol settings, makes me well-suited to diagnose and resolve this specific connectivity challenge. I am confident I can pinpoint the exact cause of the handshake failure. My approach will involve meticulously examining the network traffic during the connection attempt to identify where the TLS handshake falters. This will likely include reviewing ngrok’s tunnel status, analyzing Wireshark packet captures for specific error indicators, and scrutinizing SQL Server's network configuration and protocols using SQL Server Configuration Manager. Upon successful resolution, you will receive a fully functional ngrok TCP tunnel providing stable remote access to your SQL Server, validated via SQL Server Management Studio. Additionally, I will provide a clear, concise document detailing the root cause of the problem and the specific solution implemented. This will empower you to replicate the fix if needed in the future. I am available for immediate screen-sharing sessions to commence debugging and am eager to restore your remote SQL Server connectivity.

Helllo I prioritize the features that matter most and ensure I have the capacity to deliver them effectively. I have experience troubleshooting SQL Server networking, SSL/TLS connectivity issues, Windows server configuration, and network traffic analysis. I’ll analyze the connection flow using SQL Server logs, network configuration, ngrok settings, and, if needed, Wireshark captures to identify exactly where the TLS/SQL handshake is failing. Thanks

Bid amount and timeline above are rough placeholders , we'll firm those up once we take a look at what's happening. We've seen this pattern before: ngrok TCP tunnels and SQL Server's TLS/SNI negotiation don't always play nicely, especially when SQL Server is configured to force encryption or when the Named Pipes vs. TCP/IP listener order causes unexpected behavior. Local connections work because they bypass all of that entirely. The handshake drop you're describing almost always traces back to one of a short list of culprits , SQL Server's certificate validation, the TCP port binding in SQL Server Configuration Manager, or ngrok dropping packets it considers malformed during the TDS protocol exchange. Here's how we'd approach this: - Wireshark capture: We'll run a capture on both ends during a connection attempt to pinpoint exactly where the handshake dies , whether it's a RST from ngrok's side or a SQL Server protocol rejection. - SQL Server Configuration Manager: Check the TCP/IP listener settings, the encryption enforcement flag, and whether SQL Server is bound to the right adapter and port that ngrok is forwarding. - ngrok config review: Verify the TCP tunnel flags, any inspect settings that might be interfering, and test with a plain passthrough to rule out ngrok-side TLS inspection. - Firewall and Windows Defender rules: Confirm nothing on the Windows side is resetting inbound connections that arrive via the loopback-forwarded ngrok traffic. - Write-up: Once the fix is applied and validated from SSMS remotely, we'll hand you a short doc covering root cause and exact steps so you can replicate it. After the screen-share session and once the fix is confirmed, we can send a quick written summary with the exact config changes made. Want to jump on a screen-share call this week and walk through it live? Best, 96 Studio

✅The best approach✅ is to debug the connection at the handshake level first, then isolate whether the drop is caused by SQL Server TCP settings, TLS/encryption requirements, ngrok TCP forwarding behavior, Windows Firewall, SQL Browser/port configuration, or client connection string settings. I can help troubleshoot the SQL Server remote connection over ngrok using SQL Server Configuration Manager, SSMS testing, Windows Firewall rules, ngrok logs, SQL Server error logs, and Wireshark/TCP capture if needed. Since local connections already work, I’ll focus on the network path between the remote client, ngrok tunnel, and SQL Server listener. I’ll check TCP/IP enablement, fixed port vs dynamic ports, encryption settings, certificate/TLS behavior, login mode, bind address, firewall permissions, ngrok TCP command/options, and SSMS connection format. Once the exact failure point is found, I’ll apply the cleanest configuration fix and validate a stable remote login through SSMS. Deliverables will include a working remote SQL Server connection via ngrok TCP tunnel and a short root-cause note explaining what was wrong and how to reproduce the fix on another machine.
