Right so I figured it wouldn't be a bad idea to detail how to connect to the cubeworld server and why you sometimes can not connect.
There's two ways to connect to the server, through tunngle (Premium Network, NedStar, Polar) or through server.theicecave.net
The tunngle network solution is a bit of a hassle but the best solution if your IP is constantly changing. Not many people have a static IP. That being said a none static IP will generally stick with you for a long time depending on ISP.
The tunngle network requires no white listing and will always allow you to connect.
You can connect directly over the internet IP by connecting to server.theicecave.net. This however requires IP white-listing as I do not want random people to join. With no password solution in place this is a bit of a hassle but the only viable online solution right now.
The IP white-listing however requires manual verification by me, this means when you try and join the server you are blocked by default. So it's paramount you convey your ip when you try and connect either through forum PM or by giving me a shout on teamspeak.
If your ip is dynamic and changes on a daily basis then this solution is not for you and I highly recommend using tunngle.
Lastly their are a few issues on my end with my ISP that I'm working on resolving. Sadly my ISP tech support is crawling slow at times. In short my modem likes to self destruct on itself making connecting impossible. I'm pretty watchful on this atm but it can obviously happen when I'm not there that the modem flat lines.
Lastly x2, cubeworld servers are not too stable right now. If I see a lot of crashing again today I will allow admins to reboot the server so up time can be improved.
As always thanks for reading and if you got any questions let me know.
