If you have the server resource pack enabled in your settings, it should automatically apply when you join the GhibliCraft server.
The server IP is Play.GhibliCraft.com and the recommended version is 1.16.4, you'll need a non-cracked Minecraft account to play.
Could you explain the issue with joining the server a bit more? Does the link give any more information other than that?
If you have Discord, you can also reach out to us on the Alan Becker Discord server.
