Help request

Problem
I can use a Netherportal in the Nether to get back to the overworld. But I cannot use a Netherportal in the overworld to get into the Nether. The End portals do not work as well.

What I have tried
Linking the world with one another.
Only linking in one direction.

Please follow the issue template. Server logs, and output of /mv version-p is missing.

There you go updated the request

You need to link the portals both ways, so Utopia -> Destopia in your case. As for end portals, I don't see any linking done so link them if you want them to work. You may need to set respawn world if you don't respawn at overworld from end/nether, see Multiverse/Multiverse-Core#2160

Yeah I know. I removed the link for test purpose. It still does not work if they are linked. As I already stated above

I linked the world again, tried it, still not working. I edited the request again. New Startup log now with the try to use a portal.

Tested it on latest version of papermc and MV installed, cannot reproduce, netherportals worlds just fine with linked both way. So I can only see an issue with your setup.

1. Ensure that allow-nether is true is server.properties
2. Ensure the default nether is loaded.
3. Link them correctly (2 ways not just one) as I said.
4. Test with only mv installed, plugin conflict could have cause it.
5. You are using some 5.0.0 UNKNOWN build, no one released such a built, not even for beta testing yet so...
