Symptoms: The portal does not teleport, it teleports to the wrong place, the portal link is broken, players cannot reach the Nether

Possible Causes

  • The Nether world is disabled or not loaded in Multiverse-Core
  • allow-nether=false is set in server.properties
  • WorldGuard or a region protection is blocking portal use

Step-by-Step Fix

Step 1

Check the allow-nether setting in server.properties

bash
grep allow-nether server.properties

Step 2

If you use Multiverse, confirm the Nether world is loaded

bash
/mv list

Step 3

Check the Multiverse Nether link and recreate it if needed

bash
/mv create world_nether nether

Step 4

Check the use flag on the WorldGuard region — portal use may be blocked

bash
/rg flag __global__ use allow
