What is “Error in Establishing Connection” in TDS?
This error typically appears when:
- The TRACES WebSigner is not installed properly
- EM Signer is outdated
- USB token driver is missing or corrupted
- Browser compatibility issue
- Token not detected by system
Most users think it’s a technical server issue, but in 90% of cases, it’s a local system configuration problem.
Step-by-Step Solution to Fix the Error
Step 1: Check USB Token Connection
Make sure:
- USB token is properly inserted
- Token light is blinking
- Drivers are installed correctly

Step 2: Download TRACES WebSigner
- Login to TRACES
- Click on Downloads
- Go to Requested Downloads
- Scroll down to find TRACES WebSigner Setup
- Download and install it
Even if EM Signer is already installed, reinstalling the latest version is strongly recommended.
Signer tools are updated regularly, and outdated versions create connection errors.
Step 3: Run EM Signer as Administrator
After installation:
- Right-click EM Signer
- Select Run as Administrator
- Keep it running in background
Then open a fresh browser tab and try signing again.
Step 4: Use Google Chrome Browser
From practical experience, Google Chrome provides the most stable compatibility for TRACES signing.
Avoid:
- Very old browser versions
- Unsupported browsers
- Multiple browsers running together
Why This Error Happens So Frequently
Based on my 11+ years of experience in DSC processing and compliance support, the most common causes are:
- Users installing token drivers from random websites
- Not updating WebSigner
- System format without reinstalling drivers
- Antivirus blocking signer tools
- Using expired or incorrectly configured Class 3 DSC
Most of these problems can be avoided with proper guidance.
