Hello! I'm using ProtocolLib (latest version), paper server (Win11 22H2, Minecraft 1.21.4).

When I log in to the server, I get the error "Unable to connect to the server. Disconnecting"

Log:
log.txt

The error in the log does not affect the work. It occurs due to the use of VPN. Without VPN there is no error, but the result is the same

I fixed it, it was necessary to use version 5.4.0 instead of 5.3.0
