Make sure the client has time to respond to the player info packet.

Quellcode durchsuchen 
Apparently, Minecraft 1.13 can take a little too long to respond to
Velocity's player info forwarding packet. This especially noticeable in
offline mode: by the time the client does respond, Velocity has already
completed the login process and tried connecting to the server (it is
very quick under offline mode).

Noticed by Leymooo.
