I don't know why it happens. This may need some investigations to gather enough evidences to resolve.

I use VIAaaS as an MiTM for connecting BungeeCord with my custom server. This occurs on the proxy. I did suspect it as my custom server's issue, so I swapped to an Spigot server and had no luck.

Here is the proxy's config
