 Symptoms

• Unable to connect to Internet
• Proxy issues
• Off line mode
•  Receive this error: “WorldWide Telescope does not detect an Internet connection. Only cached information is available and some functions will not operate without an internet connection. Switching to off-line mode.”

Cause

• WWT reads the connection settings in Internet Explorer. Some people behind firewalls and proxy servers are unable to change their settings in Internet Explorer.

 

Resolutions

There are two possible resolutions for this issue:

Resolution 1

Go to Internet Explorer-> Tools -> Internet Options -> LAN settings and check the “Use a proxy server for your LAN” (See screenshots).  NOTE: Do this in Internet Explorer, even if your browser is not Internet Explorer.

 

 

 

Resolution 2

Hotfix Overview

This hotfix fixes Install issues, allows proxy configuration, and solves “install for everyone” issues on Microsoft Vista,.

Download

There are two methods to install this hotfix.

1.       Download and run this Hotfix: http://content.worldwidetelescope.org/update/wwtsetup.msi

2.       In WorldWide Telescope click the down arrow under Settings and click “Check for Updates”

If you are behind a Proxy Server you will need to make a change to your browser.

 

For Firefox: Select Menu Item Tools >> Options

Select Advanced Tab, then Network

Under Connection Select the Settings Button

Select Auto-detect proxy settings or use manual settings and specify your proxy sever

 

For IE users: Select menu Item Tools >> Options

Select the Connections Tab, LAN Settings

Select Use a proxy server for your LAN and then specify your proxy name and port (Usually 80)

 

My options are already set just as described above, but I still get the same message.

 Normally when I launch a web page I have to enter a password for the proxy server to allow connection, this doesn't happen when i launch wwt.

 Thanks.

Check this post. We are looking into this problem.

Thanks for the post

 Hi,

 what is a Proxy server??  

how do i find out? i have a wireless router at home, .. what is it ? :(

complicated...for a noob

i just wanna see the space

 

moses 

 I am behind an NTLM authenticated proxy,  with a configuration script, and cannot connect either.  Please help.  have run out of ideas. 

 

Is it possible to put the interenet connection config within the app.. rather than depening on the IE settings ? 

i don't think i'm behind any proxy. i'm using this from my home connection through a wired router

i play around, and entered a proxy address...

the "not connecting to internet" box appear no more.. but i have another problem now :)

 It's hard to get to space..

me too..

but i tried it anyway.. i entered "proxy.singnet.com.sg" (because my ISP is Singnet.com) and uses the port 8080

it works i think.. the error is gone..

We are looking in to both of these issues. We should have more information soon.

Tried your recommendations, did the changes and still get the  message  "WWt does not blah blah blah"  what can I do now?

Yup, me too. Proxy works fine for all other internet destinations. It would be nice to have an entry in the setup section where the internet parameters could be manually configured.

If it is any help to you I cannot connect to the Internet using a Microsoft ISA Server (our default set up for IE) but using the built in Squid Proxy Server on our Firewall I can with no trouble.(Techies need a backdoor). As a check I downloaded a guided tour using the Squid Proxy and then changed back to the ISA Server Proxy and tried to download the second guided tour with no luck.  This reply was sent with the Proxy set to the ISA Server just to prove Internet connectivity.

 Why do I need to make this change?  I'm behind a firewall and this function is greyed out for me.

Edit WWTExplorer.exe.config
just before the closing tag include the text bellow (with the needed changes)

<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy proxyaddress="http://proxy_server_address:proxy_server_port" bypassonlocal="true"/>
</defaultProxy>
</system.net>
chage proxy_server_address to your proxy server

and

proxy_server_port to the port the proxy is working on


If the proxy does not need authentication remove useDefaultCredentials="true" (but probably will also work with it)

Hope this fix
