Hi ClassiCube community,

Recently I started up my own server using McGalaxy materials yesterday afternoon (10/16/16). Everything has in general been working fine so far, and I haven't run into an issue that I have struggled to solve. Until now. It appears that my server is able to start running fine, but when I try to connect, I get the message: unable to establish an underlying connection. Maybe a little background leading up to this issue:

I left my house this morning around noon and returned at about 3:00 PM. My server is run on my laptop, and so today I tried to keep the lid open, making sure the settings were set so my computer never went to sleep. I came back and got some confusing dialogue box message, but I had no clue what it said. I closed everything because I imagined it someway or another stopped working, and after waiting about 5 minutes, I decided to put it back up and try and log on. Alas, I was bombarded with a red screen displaying the above message.

Does anyone know exactly what this means (in dumb people terms) and how I can go about fixing it? I currently have all ClassiCube materials: both my server console and the CC client, closed down. Maybe after waiting a solid hour, it'll start working again... but in the meantime.. anyone know of any solution?

Thanks so much! Pillow_Ninja
