If you were banned from the server, it would have said so in the msg you saw. Connection refused could be as simple as the server is full.
Now, since you seem to expect an answer within a brief time frame, mite i suggest you use the search feature here, set it to All Forums and expand the date range with perhaps the word connection or refused as search term. Many questions have been answered repeatedly, in this case there are threads at the top of the connection area going into connection errors.
