Clixserver has been so temperamental.
I'd like to help you, or at least reproduce the issue but I have no idea at all what you mean here. I Googled "Clixserver" and mostly got results about online advertising. That's probably not what you meant :-).
Let's take a step back. If you could describe what you are trying to accomplish on what sort setup and how you are going about this? I'm getting the feeling a network is involved and that you are getting issues with something that formerly worked?
Yours,
Kas.
