Beta ZimaOS issue

Hi,
running ZimaOs 1.7.0 beta2 on Proxmox 9.2.5.
After installing some app the message “Checking contaier status” pops up, and after about 60 seconds

this is the result: “Service unavailable”
I’ve tried reinstallling and sometimes some apps boot up (nextcloud, Mariadb) but randomly, and not all.

Any idea?
Thank you
