If you use the /publish command with port-forwarding, players are not able to join the world.
Version: 1.16.2
MultiConnect 1.3.14

You are three versions out of date, please update to the latest version of multiconnect and tell me if it still happens

Cannot reproduce. I didn't test with port forwarding but I doubt that would make a difference. Are players joining on the correct version? Multiconnect doesn't do serverside translation

I'm sorry about not responding for a while. I haven't had others to test that issue. The latest version seems to not allow me to join a paper server that allows 1.8-1.13
However I want to test without any other mods installed to make sure.

Hm, you should be able to connect with the 1.11, 1.12 or 1.13 protocol, although you may have to explicitly set the protocol (it's impossible to auto-detect).

I tested it with all versions in-between and when I dropped back down to the version I had it was working.

Is this a public server? If so, what is the IP? If it's a private server, what version bridge do you have?

Sorry but the server I was testing with is changing constantly which is not helpful... They're still in development. I'll do more tests and get back to you. I'm not helping too much am I? 😅

I guess that's problem resolved? We can close this then.

@Shroototem So you're playing on a server, or on a LAN server?

LAN server with the port open.

The issue seems to have been server-side and they fixed it. ( Plugin servers... Yuck )
About the /publish command, I really don't have others to help me test it. I just noticed it wasn't working properly and I'm assuming it's working properly in the newest version.
