When users use subdomain as domain while the is part of the other user domain 
nano /usr/local/hestia/data/users/mir/web.conf
DOMAIN='abzal.net' IP='217.217.248.184' TPL='default' SSL='yes' DISK='0' BW='0' SPND='no' DATE='2026-01-31' ALLOW_USERS='yes'
// Need to add this part only at the end of the line above: ALLOW_USERS='yes'
grep abzal.net /usr/local/hestia/data/users/mir/web.conf

The "SFTP channel closed by server" error on HestiaCP is usually caused by the SFTP subsystem in SSH config. Adjust it like this:

  1. Edit SSH config: sudo nano /etc/ssh/sshd_config

  2. Set the SFTP subsystem
    Find the line starting with Subsystem sftp and set it to: Subsystem sftp internal-sftp

If it’s missing, add it. If it uses something else (e.g. internal-sftp-server or /usr/lib/openssh/sftp-server), change it to internal-sftp.

  1. Restart SSH: sudo systemctl restart ssh
