Hi Rose,
Sorry for the late reply but the reply time from facebook team was not fast at all.
1) I have spoke with facebook team and when tried to login with facebook the request was done multiple time, for this reason the app has been blocked. At the same time there is ongoing the verification of the business to allow Adv campaign and similar
2) I spoke with hosting provider ( 1&1 Ionos) and currently there are no block on google api from their side. I am investigating on VPS if there are any issue in configuration. -> Update: I managed to solve this issue checking the Plesk Panel. ModSecurity Rule in Plesk normally block social login by default, you need to add manually the switch off on rules 210580. After i have done this the google login is working as expected.
