Apple Push Services certificate is not trusted

Hello there

I'm having a problem that I don't understand and I can't solve the problem.

I am using Onesignal in my application and the push certificate has expired. When I want to renew it, I create a new Sandbox & Production certificate, when I download the certificate and open it in keychain access, certificate is not tusted appears.

How can I find the problem?

https://stackoverflow.com/a/71216752 There is a solution here, when I apply it, it becomes trusted, but when I want to install it from the Onesignal panel, it gives an error.

you should download the G4 cert from https://www.apple.com/certificateauthority/ to update on your machine then it fix the issue. the notification description is on: https://developer.apple.com/cn/support/expiration/
