gitpushfailswithdenyupdatinghiddenref

I've a repository for my dotfiles and went to push changes from a branch only to encounter...

$ git push
Enumerating objects: 46, done.

 ! [remote rejected] kimura -> origin/kimura (deny updating a hidden ref)
 ! [remote rejected] master -> origin/master (deny updating a hidden ref)
error: failed to push some refs to 'git@gitlab.com:auser/dotfiles.git'

This thread suggests its because pull requests made on origin and links to a blog post with solution of how to skip this, although I do not explicitly have refs/pull in the path thats being rejected so it may be a different issue but I couldn't find much info on this so figured I try the proposed solution and updated my config to...

    [core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = git@gitlab.com:auser/dotfiles.git
        fetch = +refs/heads/*:refs/heads/*
        fetch = +refs/tags/*:refs/tags/*
        fetch = +refs/change/*:refs/change/*
        pushurl = git@gitlab.com:auser/dotfiles.git
        push = +refs/heads/*:refs/remotes/origin/*
[submodule "oh-my-zsh/.oh-my-zsh"]
        url = https://github.com/robbyrussell/oh-my-zsh
        active = true
[branch "master"]
        remote = origin
        merge = refs/heads/master
        pushRemote = origin
[branch "kimura"]
        remote = origin
        merge = refs/heads/kimura
        fetch = +refs/heads/*:refs/heads/*
        fetch = +refs/tags/*:refs/tags/*
        fetch = +refs/change/*:refs/change/*

But the problem persists. My branches are...

$ git branch -a
* kimura
  master
  remotes/origin/kimura
  remotes/origin/master

The host I'm trying to push from is where I started the repo before mirroring to Gitlab.
