We are having issues (especially during connection/login) where we are getting errors such as: "lost connection: Timed out"

This is likely because the server is on the opposite side of the world to the users that are having issues. Once they manage to connect, things are generally fine - it's just the initial connection, and often after a few tries they get on.

I have seen that others have also encountered this, and Spigot has add-ons that make this time out configurable.

My request is to support something like this natively in the Minecraft Server to allow the login timeout to be increased as desired (or default to something much longer than 30 seconds).

I have searched and seen others with similar issues, some of which have been closed as support problems. However I consider this to be a bug/feature request to allow players at long distances to still connect to a server.

This is an example log of the issues occurring:
