Update:
SI-GUI version: 5.0.0.2
OS: Windows 7 Home Premium SP1 x86

Same error and exception :(

Do you know a proxy server to test this with?

> Do you know a proxy server to test this with?

1) From an elevated command prompt run the following dummy config:
netsh winhttp set proxy "127.0.0.1:8080"
2) try to open a web page (an error will occur)
expected: no connection (ERR_PROXY_CONNECTION_FAILED)

3) Test SI-GUI and try to update the list of versions

If the browser works, setup the proxy address and port via "Control panel -> Internet options -> connections -> LAN settings (in my case)" and repeat the steps 2 and 3.

Just to be on the save side: How to undo this?
In other words: It seems, that you want me to setup no uinternet connection... I do not know why it crashes, but if it is the same behaviour when you are offline, that would help a lot :)

Hi Florian,
about the proxy

from the command line:
* To enable the proxy server (with a dummy server): netsh winhttp set proxy 127.0.0.1:8080
* To check your proxy server setting: netsh winhttp show proxy
* To remove the proxy server setting: netsh winhttp reset proxy

In some cases the settings from command line are bypassed. Try to setup the proxy directly via control panel.
To remove the settings untick the checkbox and try to use the browser :)

An update for you. You're right, the crash has the same behaviour when you are offline. ;)
Let me know how I can provide more informations to you.

Reproduced in 5.0.0.3.
I had to set a proxy as described at the end of Comment 4 to finally not have connection (I did it in IE, but it's the same thing as in CP).

Does SI-GUI work if IE works?

SI-GUI relies on the proxy set on Windows / IE. Updated the proxy fetching behavior.

Hi Florian,
it's been a while since I have used SI-GUI... today I've updated to version 5.0.0.9 and I'm facing this exception now. OTOH, Internet Explorer works...
I'm running Windows 7 on virtualbox. Don't know if this might affect...

Actually, my problem was

System.NullReferenceException: The requested security protocol is not supported. which was related to .Net Framework 4.0. Solved it by removing it and installing .Net Framework 4.5

Hi Xisco,

That issue is fixed. The C# version of SI-GUI is no longer supported, I want to migrate people over to the Java version. When the temperatures are getting lower, I am planning to restructure it a bit...

But I do not plan to fix bugs in the original SI-GUI.
