Hey there
@Harmonieslays,
You can join the server via the
Java version of Minecraft using any version between 1.10 and 1.13. We suggest
1.12.2.
If you need help changing your version, a guide exists
here.
From there the IP to join is
play.potterworldmc.com.
Let us know if you have any further difficulties.
Regards,
Harrison.
