WebUI is not updated

[qsoe]

Since the new year, the WebUI does not show the latest data. The upload speed is constantly shown as 0, the last torrent is in "Stalled" status. When viewed directly, the torrent is finished, and there are several things uploading.
The behavior started in 2024, definetely not with the new release that I installed on December 9 (qbittorrent_4.6.2_x64). I tried restarting qBittorrent, the whole machine, on both ends, nothing helps. The funny thing is, it is not stuck on 2023-12-31, it is more random:

• The last torrent is shown as Stalled, in reality it should be Sending
  The second to last torrent is not shown at all
  <here was a restart>
  The third to last torrent is not shown either
  Older torrents are shown normally

I use HTTP, not HTTPS, if it matters.
When I try to remove a torrent through the WebUI, it is removed from there, but is still shown on the machine where qBittorrent is running. If I exit qBittorrent, and restart it, the removed torrent is no longer visible. So some communication still happens, just not immediately.
Has anyone seen something like this before?

Version 4.6.3 seems to have solved it.
