Well if /home/server/logs/mproxy.err is clean (no errors), I can only suggest to change from 44501 and 44601 to 29000 and 29001 (in Conf.xml and /server/patcher/serverlist.txt), and change 29000 and 29001 to other ports (in /glinkd/gamesys.conf and Conf.xml). If this doesn't work, then try downloading client below, but I don't think it's a client issue if it connects fine to 29000. You using vm or remote host?
where to change the ip address if there is a virtual machine?
