ViaVersion Dump

• Type /viaversion dump, and put the link here.
  client(1.16.5) whatever it is fabric or forge or vanila can join my server.

Additional server info

• Is server using a proxy (eg. BungeeCord/Velocity)?
• no
  What software is it using and what plugins? (Debug HUD may have it (F3))
  i can't login in my server
  Are you running on client-side mode?
  no,it's server-side mode

when client is logining in the server, it's just like this

Closing this issue due to the following things:

1. There is no viaversion dump of this meaning we can't figure out what's clearly wrong,
2. This is likely to be a third-party plugin/mod on the server itself that may be causing viafabric to fail,
3. Should this issue continue to happen, Please send a response whenever needed.
