I cannot reach modded server I was playing on yesterday

[scullyluke 0]

Hi everyone, I am new to this forum and fairly new to DAYZ with about 200 hours on the game.

I recently started playing on my first modded server and it is really good.

Problem is, today I tried to join and it will not let me in, even though I was only on it yesterday. 
 

I would love to paste a screen shot up here, but this forum does not seem to have a tool for pasting pictures. 

Can anyone offer any advice?
