Push function disappears after push certificate replacement

I got the following mail from Apple.
"Your Apple Push Services Certificate will no longer be valid in 30 days. To generate a new certificate, sign in and visit Certificates, Identifiers & Profiles"
I received a new push certificate and registered it in the keychain. However, there seemed to be a problem with two certificates. I deleted the certificate that is about to expire because I could not receive the push message.
Still, the push did not come, and in the process of doing some settings, I found that the push reception setting did not work at all.
  • How do I set it up?

Various settings and phenomena that appear on the smartphone can be checked from the link below.
