'GitLab: Commit must be signed with a GPG key

I've faced an issue with GitLab, and I don't know how to fix this issue. I'm owner of repository, I've already gpg enabled, but at the end I still face an issue. Here is my global configuration for my git:

[user]
    name = neon
    email = [email protected]
    signingkey = 244F9F35
[init]
    defaultBranch = main
[gpg]
    program = gpg
[commit]
    gpgsign = true
[credential]
    helper = store --file ~/.git/.my-credentials
[pull]
    rebase = true

Error:

remote: GitLab: Commit must be signed with a GPG key
To https://gitlab.com/some_name.git
 ! [remote rejected] cm -> cm (pre-receive hook declined)
error: failed to push some refs to 'https://gitlab.com/some_name.git'

Regarding GitLab it self, GPG key has been assigned, and in use
