Hi,
Please open a support ticket, that would be easier to assist (you can also open a support tunnel so we can remotely access your XOA to investigate faster, see https://help.vates.fr/kb/en-us/9-xen-orchestra-appliance-xoa/16-create-a-support-tunnel )
edit: don't forget to go in XOA/Support then doing an XOA check, see https://help.vates.fr/kb/en-us/9-xen-orchestra-appliance-xoa/17-xoa-check
