This usually means there is a network problem. Either your network is blocking port 5998 or your router may just be having issues that need to be corrected. If you live in a dorm or are playing from a public network, it is probably going through a proxy and that means they are most likely blocking port 5998, so you won't be able to play. If you are playing from home and have control of your internet connection, then the problem is probably either with your router/modem or with your PC. First, make sure that you don't have a firewall or any other security programs running that might block your connectivity in any way. Next, make sure you aren't forwarding port 5998 to any PCs on your network (this includes port range forwarding that would include port 5998 in the range). If not, next you want to try powering down your modem and router. Then power up your modem and wait until it gets a connection. Next, power up your router and wait for it to connect. Last, reboot your PC and try connecting to EQEmu again. If that still isn't working, then there is a good chance that you need to reset your router or router/modem back to factory defaults. Most modems have a sunken in button that you can hold down to reset it to defaults. Check your product documentation for how to do it. Once that is done, set up your router again and try connecting to EQEmu again. It should be working now, but if not, there may be an issue with the routing from your ISP or your router may just be going bad.
