Not Connecting to the Internet, Proxy issues, Offline Mode?

Excuse my ignorance  .......... but where does this text need to go exactly?  I've opened the WWTExplorer.exe.config file but am unsure where exactly to put those lines

just before the line </configuration>

I am putting together a descriptive fix for this now... thanks Jacques!

Here are the fixes... also in the first thread of this post.

 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.”CauseWWT 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 2Thanks to Microsoft Research Community user JacquesE for this suggestion! Follow these steps carefully. If you don’t feel comfortable editing this file find someone that does. NOTE: Colors are for description purposes only, your colors may vary.

1. Using windows search, search for “WWTExplorer.exe.config” (This file can also be found in your Program Files\Microsoft Research\Microsoft WorldWide Telescope folder)
2. Open the file and scroll down to the bottom
3. Copy the code below just before the last statement:  </configuration>
4. Edit the http://proxy_server_address so that it reflects your proxy server address
5. proxy_server_port Edit the  so that it reflects your port number
6. If the proxy does not need authentication remove useDefaultCredentials="true"
7. Save the file
8. Launch WorldWide Telescope

Code:

<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy proxyaddress="http://proxy_server_address:proxy_server_port" bypassonlocal="true"/>
</defaultProxy>
</system.net> Examples:  Before:

After:

 

This is all great for people with proxy servers  But I do not have a proxy server and every program except WWT finds internet connection. Any advice for people like me?

 Hi all,

I'm *still* unable to get WWT to go online here at work. The 1st fix is irrelevant since I'm already online. :)  {Auto detect settings is turned off, however. Does that make a difference? That's how the network folk set it up before I got the pc} I tried the 2nd fix (editing the wwt config file), but to no effect. I'm behind a proxy that requires authentication (login & pwd the 1st time I run software that tries to access the outside world in that session). I do have admin rights on my pc but not the network.

cheers,

I am at a school using a proxy server but it is accessed using a configuration script, there are no entrys in the proxy server or port boxes. I have tried editing the wwtexplorer.exe.config file with some proxy settings that the IT guys gave me but all I get is an error message telling me the program has to shut down. Would there be some alteration to the wwtexplorer.exe.config that would use the address for the script rather than the proxy address. The problem is that for new sites I usually get asked for my user name and password which doesn't happen when  wwt is launched.

Btw brilliant site which I am enjoying at home, just wish I could show them at school. Cheers.

Try setting Internet Explorer as your primary browser and following resolution 1 in the first thread.

To danny76: Sorry to ask, but are you sure there is no proxy present, maybe the ISP configured one for you you can't remeber or are not aware. You can contact them or check IE settings for one. (Again sorry for asking). .

To Marayong: if you need to provide user/pwd then the application needs to ask them and then send them to the proxy. There is no way to provide them in the config file (and doing so would be a security problem for you)

To:zaphod:You can probably ask the IT guys for proxy address and port instead of pac file, but if you do need to provide user and pwd you're in the same situation as Marayong.

To all 3:

1) Can you get more info on how the net you're on is connectd to the world ? (Here we have an ISA configured both as firewall and as proxy but this change in the config file would be needed even if ISA was not providing any proxy service but still by just being there)

2) Maybe instaling a local proxy, pointing WWT to this local proxy and configuring anything that is needed to surf the net in this proxy will help. This is a last option solution!

G'day,

I'm on sick leave the next few days so can't get any further network details. :(  The IT folks are also flat out at the moment installing new hardware around the campus so I'd not have much chance of getting anything out of them at the moment.

Your earlier post indicated it would work with proxies that did and didn't require quthentication, so I thought it worth a try. From what you say it doesn't work with proxies that require a login and password.

Your last option of setting up a local proxy sounds interesting. I've never needed one myself (just fought with them) .. are there any particular ones you could recommend? (Freeware/open source pref). Something that would redirect requests from software on my machine to the network proxy, adding in the login & password, either automatically or prompting for it? Even if I have to run them inside a "sandbox" on my machine. There's nothing to hide so I'd rather not bother with anonymous proxies. My pc is in a secure area (strictly no go), only I use it and it's locked whenever I'm not around .. so security is less important than functionality in this case. :)

cheers,

David

 

 

I have tried the altered configuration script with proxy settings supplied by IT guys but to no avail. The problem is the user and password dialogue box does not appear as it usually does when opening up Internet Explorer and as Jacques has pointed out it is here that I am stuck. Thanks to the prompt and helpful replies, maybe in a later release version this will be addressed. Still a brilliant application and of course will only get better with time. Cheers.

 Hi zaphod,

We are aware of the proxy "username/password" issue and we will be looking into it. Please keep checking the first thread in the Not Connecting to the Internet, Proxy issues, Offline Mode? post for updates.

We are trying to understand if these "Proxy User name/Password" dialog boxes are a Web based pop-up or program dialog pop up. If anyone is able to have their IT people help us understand your system and needs, please send me a private message by clicking on my name.

Thanks,

I'm absolutely positive that I have no proxy. I'm on AT&T U-Verse and everything is connected to the Internet except for the WWT. I tried to configure my setting to use an external proxy but got the same result.

However when I've tried to use the address of my router as a proxy server I got this: "The Imagery data file could not be downloaded or has been corrupted. WorldWide Telescope must close. You need a working internet connection to update this file. Try again later".

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

Done all of the above, but still doesn't work.

Our proxy server is a Navaho box, which runs on Linux, but authenticates against Active Directory. Normally it uses the default logon credtientials of the computer, dropping through to a logon dialog if the user is not recognised. I.E. works fine.

however WWT still says it cannot detect a network connection.
