APNs auth key doesn't work

Hi,
I use Firebase Cloud Messaging for Push Messages implementation. Following the isntructions I have created APNs key, but iOS devices didn't receive notifications. I have started to explore the problem and found lola tool to test APNs using terminal. Unfortunately that doesn't work as well.
Using this command:

lola \                                                  
> -bundleId com.myCompany.myGame \
> -device fbihwxcBv0mMuhuwh_mld8:APA91bGN7nsVT56NTXnKovw30OR9mizCY1gxkO44_1a3iGoMBhj-DhOGiBUzmknbFLXZAkNJpJSmT7dA9qu7sAsppl8X0mXXXFXxWnpKRiMh6gw_OiEzG0JB \
> -teamId B48K99R7Y4 \
> -authKey APNs_AuthKey_ACY8UN9XKG.p8 \
> -message "Test"

I receive error:

Error: Invalid response Optional(<NSHTTPURLResponse: 0x7fac36f13ce0> { URL: https://api.sandbox.push.apple.com:443/3/device/cOo139R3P0GljlBEsgTsij:APA91bGHGYKinOmgQOQyiuepoVLBgx_xoKhiDmgPn_2292Z3HnPvstoJSvt96tlfxACArZRHvH1hCX3pkKFJAk8zDVldwLj_YY0wd8NH5S7lxYn3mO3ZJogKqmSjhUD31JLWHp1eCTKC } { Status Code: 403, Headers {
    "apns-id" =     (
        "19B38491-2180-5C2B-9940-2B53520F9CA8"
    );
} })

What can be the problem? All certificates are active and I able to push builds to TestFlight

I'm having the same issue. This was working for me before. I switched to an upgraded Macbook and VSCode from 11->12. I have the APNs key generated and loaded into Firebase per instructions. But I'm getting this error when trying to push messages from a cloud function:
messaging/third-party-auth-error.
I've checked out everything in this post and it still doesn't work.

Anything else I should be checking?
