Problems connecting to server, getting kicked off

I'm running a small snapshot server with a few people, and we've been experiencing people having trouble joining the server. They join for a few seconds and then disconnect. It's hard to find out what the issue exactly is, but we cannot reproduce it in 1.16.5 on the same server, with the same people.

After a reboot, the problem seems to be gone for a while, only to return afterwards within a couple of hours.

Interesting thing in the console (might be unrelated of course):

[03-Apr-2021 09:54:17] {color:#ec7118}[WARN]{color} handleDisconnection() called twice

Attached are debug logs from debug start/stop, and debug report.

having the same problem on the latest snapshot, went netherite mining and a lot of things are seemingly desynced (beds not placing both blocks, blocks with fire on top, becoming ghost blocks more than usual, items not crafting properly, getting kicked, etc). i host the server from my personal computer and there seems to be no problems displayed in the server console.

This issue has disappeared. In 21w14a, the issue still seemed present. After that the worldgen changed back and it took awhile to 'upgrade' to a newer version. This newer version was 21w18a eventually and this does not have the issue anymore. All users can connect fine again.

Is this still an issue in 21w43a or later?

After 21w18a we didn't have the issue anymore, however, we have not upgraded the server to the 1.18 snapshots, so if the bug would have returned, I wouldn't know.

The issue was at least resolved before the 1.17.1 release.
