Connection refused

I am getting a lot of connection refused errors to the C2 server. As a result I am missing a lot of trades. I have gotten these connection refused errors before and I have found that the only solution is to log off C2 and log back in. Usually I am then able to get right back in but this time there were long periods where it would not let me back in.

Here is a typical java error message:

06:46:26:826: TabCollective2.reqSignals: url=

Feb 7, 2013 6:46:28 AM TabCollective2 reqSignals

SEVERE: null Connection refused: connect

at Method)

This happened yesterday morning during these times:

Connection refused between 5:30am and 6:00am MT

Connection refused between 6:46am and 7:13am

Connection refused between 7:23am and 7:34am

Connection refused between 7:45am until I shut it down at 7:55am

Has anyone else been experiencing this problem?
