Sorry to revive this thread, but i had this problem a few moments ago and found the solution...
the problem is the DNS/rDNS for the client is missing in the server.
AFAIK, when the webutil is called, somehow the server is trying to to resolve the client IP or hostname and fails to do it, throwing the connection down.
After i confirmed that the client could resolve its own IP (via /etc/hosts), i created the DNS and rDNS for the client. After that the client could connect without any problem.
hope this helps someone in the future.
