# Vulnerability Database not getting updated - "Unable to establish direct connection"

## Problem

Vulnerability Patch DB Update fails with error message -"Unable to establish direct connection".

## Cause

One possible reason could be that your Network Firewall is blocking the data as,

1. The firewall does not allow communication through port 443 and 80
2. **"patchdb.manageengine.com"** is not added to the exception list of your network firewall.

## Resolution

1. Open the ports 443 and 80 to allow the firewall to communicate.
2. Add **"patchdb.manageengine.com"** to the exception list of your firewall. Ensure that your proxy server allows downloading the following files:
   - .xml
   - .sql
   - .gz
   - .zip
   - .7z
   - .dll
   - .json
   - .exe
   - .vbs
   - .sh
   - .txt
   - .bat
   - .bash
   - .ps1
