I have a Java server set up through Aternos to play with friends, spawn used to be in an empty field area in the middle of the map and I have recently built a building near by to move spawn to. However, when I tried to set spawn there and test it, it tps me and others to the large cavern 70 blocks underneath the spawn building. I have tried the /setworldspawn with nothing added and with my exact coords, and I have tried /gamerule spawnradius 2 but nothing is working, I will try any and all suggestions people have, thank you!
/minecraft:setworldspawn (Vanilla), or
/setspawn (Essentials, also).
It is possible you have
/spawnpoint yourself. In that case, you may need to use
/spawnpoint @a clear (older versions of Minecraft/Essentials) or
