Hi everybody. I'm getting this error every time i try to load CGoban 3 on win 8 for half a year - http://clip2net.com/s/4JhOgd

KGS Admins didn't say anything useful when I mailed them, so they're useless.

Any ideas?

Maybe you have a firewall which is block the download of the jnlp. You could try downloading the jar file (which is the actual CGoban program, the jnlp is just a text file wrapper with some metadata which points to the jar) directly from http://files.gokgs.com/javaBin/cgoban.jar and running that (if double clicking it doesn't work then open a command window in the folder with the jar and run "java -jar cgoban.jar".

It appears you haven't been able to dowload the application from the site.
Cgoban is a java web start app, which means that clicking on it should download the app and run it altogether.
Try saving the file cgoban.jnlp to disk and opening from your computer. It should download the app.
Otherwise, check your java set up for updates, etc.

I've downloaded the jar-file, and applications starts... but it says that goserver.gokgs.com refuses connections when i try to log in... and i don't have a firewall except KIS - but its log doesn't show anything that blocks java...

Does your firewall block KGS's communication port( port 2379 )?

Did you happen to load kgs at a hotel or coffee shop that happens to have one of those " agree to the terms of service before connecting to the internet" splash pages? if you load kgs before clicking agree it will corrupt the cached version of cgoban on your computer. Deleting cgoban, clearing your java webstart cache and downloading cgoban again may help.

no-no, i just installed fresh windows 8 on my PC at home - and Firefox + JRE 7. And CGoban 3 doesn't work on them... i've tried to find where 2379 port could be blocked, but found nothing...

Just wanted to say thanks Mef. Campus Wifi had had troubles Saturday morning so I went to Starbucks to play on kgs. Later I found out I couldn't open sgf offline with cgoban. Fortunately I could still get on kgs so I just used opened stuff in multi go. Your suggestion fixed the error though! :bow:

Windows 8 or Windows 8 RT?

Have you tried offline installation?

In my experience with xp, if problems with cgoban crop up, they can often be solved by deleting the file from within java, and then downloading it again. I have no experience with windows after xp, but I imagine that the java control panel is the same, so open it and under temporary internet files click view and delete cgoban there. Good luck!

I don't know if it's in any way relevant to your problems, but
have you tried downgrading to JRE6?

Last time I tried JRE7 I had to gave up due to problems with KGS. :cry:

when i had this problem i noticed the icon was missing and it wouldnt launch or install cgoban. somehow it was still under installed software in windows so i uninstalled it there and then reinstalled the client via gokgs.com.

This solved the problem for me until a cgoban update happened (this would repeat itself). This was for my windows XP machine so it might not relate to windows 8 though.

so try this out, see if it helps.
good luck

Toshiro, did you try clearing your cache?

I do not think your problem is the one Mef highlights (the error message would be the html of the log-in screen of the guilty WiFi network) but it's an extremely common problem, can creep up on you in your own home, and cannot be solved in any way other than clearing the cache.

Are you sure KIS is the only active firewall? In my experience, some users have been behind two firewalls, thinking they are behind only one. Some of them did not deactivate the Windows firewall when installing third-party security software. Others have been behind a firewall at work or school, which, of course, would not apply in your case, since you are at home. Do you have a home network? If so, is there a firewall in your router?

It might not help, but if you are grasping at straws, you might try 32 bit Java for Windows if your current version is 64 bit. http://www.java.com/en/download/faq/java_win64bit.xml

It is surprising how often removing CGoban 3 from the web start cache and re-downloading it fixes problems! There is a page at Sensei's on this, which may be longer than most people need.
