If you're having difficulty sharing your webcam, or receive a message stating that you're behind a firewall or proxy server, you may have a firewall or another application interfering with the connection Yahoo! Messenger needs for using the webcam.
Please note: Using a webcam through a proxy server is currently not supported.
First, please check your connectivity settings within Yahoo! Messenger to make sure you're not connecting through a proxy server. Here's how:
- Select " Yahoo! Messenger."
- Select "Preferences."
- Select "Connection."
- Select "No Proxies."
- Click "OK."
- Close Yahoo! Messenger completely and start the program again. This should eliminate the error message.
Please Note: If you're unable to connect using the "No Proxies" option, please reverse your changes.
Are you behind a firewall? Your firewall must permit outgoing and incoming TCP connections on port 5100 to send and receive webcam video images. Please make the following changes to your firewall:
Protocol: TCP
Port: 5100
Most Internet service providers (ISPs) don't have firewalls or proxies, but you should contact your network administrator or ISP for accurate information.
Windows XP and Vista users: You may be running Window's built-in Internet Connection Firewall (ICF also known as Windows Firewall) without your knowledge.
