U232 V5 XBT peer problem

[szaby]

Hello!
I use U232V5.

OS: Debian 11 / Apache 2.4 / MariaDb
XBT port: 8888

My problem is that XBT starts working. But in the xbt_files_users table it does not write anything to the database. The client does not write an error.
The site does not show that there is a seeder for the torrent.
All torrents have 0 seeders. And it works in the client.

Where should I look for the error?

Thanks!
