I have been using this site for many years without many problems. Recently, I suddenly started having a connection problem which keeps me from connecting into the game. The message is as follows. Could anyone shine some light how i can fix it? Thanks in advance.

***Open port 5834
***Connection to port 5834 failed
***Open port 23
***Connection to port 23 failed
***Connection failure, bad connection or firewall problem
***Connection failure, change connection method...
***Attempts to work around...
