## Problem Statement
MC (Management Console) Login Error
## Issue Details
Users are unable to access the Management Console and receive login errors.
## Root Cause
This issue commonly occurs due to incorrect vendor string configuration in the database. The license retail table may contain a mismatched vendor string value.
## Symptoms
- Unable to log in to Management Console
- Authentication failure messages
- Vendor string mismatch errors
## Resolution
Steps
1. **Check Database Vendor String**
- Connect to your database
- Query the license retail table
- Verify the vendor string matches your license key (should include suffixes like 'TEST' if applicable)
2. **Update Vendor String**
- If mismatch found, run SQL update to correct the vendor string
- Example: If vendor string shows '104216' but should be '104216TEST', update it accordingly
- Verify the update was successful
3. **Restart Services**
- Restart the Management Console service
- Clear any cached authentication tokens
- Attempt login again
4. **Verify Activation**
- Confirm your license is activated for the product you're using
- Check license details in the system
## Prevention
Regularly audit your database license configurations to ensure vendor strings match your license keys exactly, including any test or environment-specific suffixes.
