Nighttime updates of Hestia are failing?

Hi,

For the last few days, I’ve been getting these cron failure emails:

Cron admin@backups sudo /usr/local/hestia/bin/v-update-sys-hestia-all

Error: hestia update failed
Error: hestia-nginx update failed
Error: hestia-php update failed

Yet when I run this manually as root:

sudo /usr/local/hestia/bin/v-update-sys-hestia-all

…it all runs through, with no errors. Any ideas on what to check?

Thanks

Andy
