Push notifications firebase does not work, sdk java firebase

When I run my code in the main class it works correctly, but in the backend this code does not work.

There are no exceptions, it shows no error.

I put impressions to see what happened, but it never shows the impression 3. java version: 1.8 server: glassfish 5

The code runs in the main class but not in the backend, I thought this happened because it was on my local machine (localhost), but I uploaded the code to the server and the same thing happens, the code does not run and shows no errors
