404 page not found, production, multi bench

Hi all,

On my Synology NAS, I installed Frappe/erpnext, deplyoment for production using multi bench, erpnext v.12.16.2.
After install, I receive “404 page not found”.
Under home/frappe/frappe-bench/logs# cat frappe.log I receive this error:
“[DEBUG] 2021-02-20 10:02:11,908 | /home/frappe/frappe-bench/apps/frappe/frappe/u
Site: plan.com
Access denied for site plan.com

*plan-com it’s not my real domain

Any ideea how to solve this issue?

Thank you.

I am not sure if I gave all the right details. Does anyone experienced this failure before?
