Phex has a Socks5 protocol implementation which is not tested alot and might not work correct.
Since the lack of testing there are many different error messages for many cases used... so usually I should be able to clearly say what the problem is...
But I cant find your error message anywhere in the Phex source...
This seems to be a Java error mesage.. but thats strange too.... since Java should not deal and know about the SOCKS connection...
I have to research some more to get Java to stop messing with my SOCKS protocol
...or maybe better completly switch to Javas own SOCKS implementation.
