I cannot get onto Skyblock

Yesterday, I was on the Skyblock server (plain old Skyblock, 1.14.1) and entered the command /classic. It proceeded to take me to the Minecraft loading screen (loading terrain) and after a few moments, told me that I had been disconnected and brought me back to the server list. Now, every attempt to log onto the server results in this same thing.
Is there any way that I can be sent back to the regular Skyblock server without being online?
Edit: I forgot to mention that I changed my Minecraft username to GreenGuy15 a few weeks ago.

 

The classic server is run on 1.8, and the new /skyblock is run on 1.12. While it will allow you to connect with later versions, they have been known to cause issues, especially with various textures as they were completely redesigned in the newer versions of Minecraft. I would recommend trying to join in 1.8 if you intend to play on the classic server, and 1.12 if you are wanting to play on the regular Skyblock server.

If changing your version does not work, please try logging on to skywars.com, and then using /servers to navigate to whichever server you would like to join.

 

Thanks!

 

Has this been resolved so I can lock the thread?
