Lost my island and rank

So I haven't played in a long time and my rank is no longer here. I believe I was a skylord prior to my ability to enchant anything I wanted to max. I just logged onto the server classic for the first time in over 2 years. I got the rank maybe 4 years ago? maybe 5? I'm not 100% sure I just wanted to come back and have a good time like I use to when I enjoyed minecraft. I just grew out of it for a bit.(got bored and also signed a contract to play pubg professionally so never really had time to play) Now I am back and would like to continue playing on skyblock as it's really the only feature I enjoyed in minecraft. What's weird though is that I have my inventory of what was left on me and my ender chest of what's inside that. Everything else is gone.
