Here’s a step-by-step tutorial to fix the “Please start the eMSigner at MCA website” error when eMSigner runs on the wrong port or is not detected in browsers.

How to Fix “Please Start the eMSigner at MCA Website” Error

Many users face issues with eMSigner not being detected by the Ministry of Corporate Affairs (MCA) website. The primary reason is port mismatch, where MCA expects port 1585, but eMSigner may run on port 2015, 8080, or another port.

This tutorial provides a step-by-step solution to ensure MCA detects eMSigner correctly.

🔍 Step 1: Check Which Port eMSigner is Running On

Before making any changes, confirm which port eMSigner is using.

1. Open Command Prompt (Admin):
   • Press Win + R → Type cmd → Press Ctrl + Shift + Enter (to run as Administrator).
2. Run this command to check running ports: netstat -ano | findstr :2015 netstat -ano | findstr :8080 netstat -ano | findstr :1585
3. Look for a LISTENING status like: TCP 127.0.0.1:2015 0.0.0.0:0 LISTENING 32984 This means eMSigner is running on port 2015, while MCA may be looking for port 1585.

🔍 Step 2: Check Which Port MCA Website Detects

To find out which port MCA is expecting:

Method 1: Check MCA Logs in Browser Developer Tools

1. Open Google Chrome.
2. Press F12 to open Developer Tools.
3. Go to the Network tab.
4. Open the MCA portal and try using DSC (Digital Signature Certificate).
5. Look for requests to: https://127.0.0.1:<port>
   • If you see https://127.0.0.1:1585, MCA expects port 1585.
   • If you see https://127.0.0.1:2015, MCA expects port 2015.

Method 2: Manually Test Ports in Browser

Try accessing these links in your browser:

https://127.0.0.1:1585
https://127.0.0.1:2015
https://127.0.0.1:8080

• If one of them works, MCA is expecting that port.
• If none work, proceed to the next steps.

🛠 Step 3: Fix eMSigner Not Detected in MCA Website

Option 1: Make eMSigner Run on Port 1585 (Recommended)

If eMSigner is running on port 2015, but MCA expects port 1585, follow these steps:

1. Stop eMSigner:
   Open Task Manager (Ctrl + Shift + Esc), find eMSigner.exe, and End Task.
2. Kill any process using port 1585:
   Open Command Prompt (Admin) and run: netstat -ano | findstr :1585 If a process is using port 1585, terminate it: taskkill /F /PID <PID> (Replace <PID> with the process ID.)
3. Restart eMSigner as Administrator:
   • Right-click eMSigner.exe → Run as Administrator.
   • Check the log to see if it’s now using port 1585.

If this does not work, proceed to the port proxy solution.

Option 2: Use Port Proxy (If eMSigner Won’t Start on Port 1585)

If eMSigner is stuck on port 2015 and MCA expects port 1585, use a port proxy to redirect port 2015 to 1585.

1. Open Command Prompt as Administrator.
2. Run the following command: netsh interface portproxy add v4tov4 listenport=1585 listenaddress=127.0.0.1 connectport=2015 connectaddress=127.0.0.1 This forwards traffic from port 1585 to 2015, so MCA detects eMSigner.
3. To verify the proxy is set up: netsh interface portproxy show v4tov4 You should see: Listen on 127.0.0.1:1585 → Connect to 127.0.0.1:2015
4. Restart eMSigner and MCA Website and test again.

📌 Step 4: Add eMSigner to Windows Firewall & Trusted Sites

To avoid security blocks, add eMSigner to Windows Firewall and Trusted Sites.

1. Add eMSigner to Firewall

1. Open Windows Defender Firewall (Win + R → firewall.cpl).
2. Click Allow an app through Windows Firewall.
3. Click Change settings → Add another app.
4. Browse to: C:\Program Files\eMSigner\eMSigner.exe
5. Allow for Private and Public networks.
6. Click OK, restart eMSigner, and try again.

2. Add eMSigner to Trusted Sites

1. Open Microsoft Edge or Internet Explorer.
2. Go to Settings → Internet Options → Security → Trusted Sites.
3. Click Sites, and add: https://127.0.0.1:1585 https://127.0.0.1:2015 https://127.0.0.1:8080
4. Click OK, restart your browser.

📌 Step 5: Test eMSigner Again

Now, check if MCA detects eMSigner:

1. Open MCA Portal and try using DSC (Digital Signature Certificate).
2. If MCA detects eMSigner, the issue is resolved.
3. If still not working, restart your PC and test again.

🛠 Step 6: (If Issues Persist) Reinstall eMSigner

If MCA still does not detect eMSigner:

1. Uninstall eMSigner (Win + R → appwiz.cpl).
2. Restart your computer.
3. Download the latest eMSigner from the MCA website.
4. Install and run as Administrator.
5. Try port proxy (if needed) again.
