Problem Description

Issue

Hello, I am having issues connecting to the server I’m creating. When I set up a vanilla Minecraft server, I can connect without any problems. However, when I try to create a server using Forge, I am simply unable to connect.

Could you please assist me in identifying what might be causing this issue?

Thank you.

Reproduction Steps

• Created an minecraft instance
• Downloaded Forge
• Inserted the modpack in the server
• Tried to join the server
