v-delete-sys-pma-sso and v-add-sys-pma-sso
and everything worked. BUT! there is an error if you use the Proxy Template to log in to the panel How to remove port number from IP address / Redirect Hestia control panel port from 8083 to 80 (Web)? - #9 by Darkle
then single sign-on stops working.
That for example cp.domain.kz / error hestia-sso.php
cp.domain.kz:8083/ everything works with hestia-sso.php
