normal client crashes, enders: Connection refused: connect

[sefer]

Tried using both java 6, and java 7, neither fixed the problem. I have also told my firewall to accept the program, and opened the ports 1870-1871 on the router. I keep getting this error.

I am at my wits end here... I am DIEING to play salem, but did not get into the beta, so now I go here and I can't even play this... Enders client tells me the connection is refused, and the normal client crashes with that error up before even reaching the login screen. I have seen TONS of threads similar to this, none helped me out, majority went unanswered. I use amd radeon so its not a problem with nvidia, I use windows 7, I tried both 32 and 64 bit clients, I tried re downloading the normal client, and take note the .bat files do not work for me in enders client, I have to run the haven.jar directly, otherwise the .bat files just open, then close, doing nothing.

I have tried fully disabling the firewall, still no luck. And I am close to putting my fist through the wall... So if you can help, please as soon as possible, reply.

Have you tried with "direct connection" at Networks settings in Java Control Panel?

[sefer]

i didn't even know java had a control panel haha. I,ll try that right now.

edit: turned it on, applied, tried again, same problem.

Also, when using enders I can actually login, but the second it changes from authenticating to logging in, it crashes instantly. Also, if I type in the wrong password, it won't crash and just says wrong password, so only when I am logging in successfully does it crash.

honestly don't know what could be causing this. Another computer I have works. Has same firewall, antivirus, java version, graphics card, windows 7, and yet it can connect, and mine cannot...

[borka]

@sefer - are both computers using the same Router to connect with Internet?

Check settings at Router...

Or is your Computer using the shared connection function of the other?

Connect your Computer direct with Router...

What about security settings in Java? It could be an issue here blocking it from going beyond the login screen. I'm just stabbing at the problem, so pardon me if I'm nowhere near the right answer.

All of a sudden its happeing to me too with enders.
Normal client works but enders is giving me a connection refuse.
