pal_user,
1) Please be sure that your proxy settings are configured properly in the MyEclipse preferences under General > Network Connections
2) Test the proxy by opening a browser inside MyEclipse (Window > Show View > Web Browser). It should navigate to the MyEclipse website (http://www.myeclipseide.com). Can you open the MyEclipse website? What about Google or some other external site you know your proxy allows access to? This will tell us if the proxy is configured correctly and just not allowing access to the MyEclipse site or if the proxy is configured incorrectly.
3) If you can get to other external sites but not MyEclipse you’ll need to work with your network administrators to allow accesses to the following sites through the proxy:
*.myeclipseide.com, *.poweredbypulse.com, *.genuitec.com
If this does not resolve the issue, please send an email to support@genuitec.com with above details, include the post weblink for quick tracing. Add tracert to myeclipseide.com. Open http://www.whatismyip.com and include your IP in email. Please be sure to include both your subscriber id and subscription code so we can assist further.
