503 error when I login or checkout [Solved]

[robs2809]

Hello everyone
since this morning (day of the start of our blackfriday) the site has started to display a 503 error from backend when I login, or when I register or during checkout while from backend when I go to edit on a product, customer.
Enabling debugging in the AJAX requests displays 503 on the url https://www.domain.it/admin/index.php?controller=AdminGformrequest

The shop is developed in PS 1.7.8.11, php 7.2

Do you have any ideas?
Thanks and have a good black friday everyone

Too many requests, server is certainly overload, ask your hosting provider or connect to hosting console to see ressources

It was a problem with Imunify360 on the server.
