Can't change bibliography heading

Question

I would like to change the heading of my bibliography. I found this thread: How to change Bibliography heading?

Unfortunately, this doesn't work for me. Additionally, I would like to remove the page header 'LITERATUR'.

\documentclass[landscape]{article}

% paper geometry
\usepackage[landscape]{geometry}
\geometry{
    a4paper,
    total={210mm,297mm},
    left=15mm,
    right=15mm,
    top=15mm,
    bottom=20mm
}

% header and footer
\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}
\fancyfoot[LO, RE] {Test}
\fancyfoot[C]{-\,\thepage\,-}
% columns

\usepackage{multicol}
\columnseprule0.5pt
\columnsep5mm

% german spelling
\usepackage{fontspec}
\usepackage{polyglossia}
\setmainlanguage[babelshorthands=true]{german}

% citation
\usepackage{cite}
\bibliographystyle{ieeetr}
% change heading of bibliography
\renewcommand{\refname}{Literaturverzeichnis}

% blind text for mwe
\usepackage{blindtext}


\begin{document}

\begin{multicols}{4}
\section*{Test}
\blindtext
Test \cite{wiki:test}
\blindtext

\bibliography{references}

\end{multicols}

\end{document}

I compile this tex file with:

xelatex -synctex=1 -interaction=nonstopmode test
bibtex test
xelatex -synctex=1 -interaction=nonstopmode test
xelatex -synctex=1 -interaction=nonstopmode test

When you use babel or polyglossia for language support, you need to add the \renewcommand for the bibliography name to the elements defined by babel or polyglossia.

\addto\captionsgerman{\renewcommand{\refname}{Literaturverzeichnis}}

It's not quite clear from your question what the problem is with the page headings. In your original code, you don't set any specific header code, so the default is used (which is what you are seeing). If you only want this header for the bibliography pages, you can set the header inside the above command:

\addto\captionsgerman{
   \renewcommand{\refname}{Literaturverzeichnis}
   \fancyhead {MyHead}} 

Here's your complete code:

\documentclass[landscape]{article}

% paper geometry
\usepackage[landscape]{geometry}
\geometry{
    a4paper,
    total={210mm,297mm},
    left=15mm,
    right=15mm,
    top=15mm,
    bottom=20mm
}

% header and footer
\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}
\fancyfoot[LO, RE] {Test}
\fancyfoot[C]{-\,\thepage\,-}
% columns

\usepackage{multicol}
\columnseprule0.5pt
\columnsep5mm

% german spelling
\usepackage{fontspec}
\usepackage{polyglossia}
\setmainlanguage[babelshorthands=true]{german}

% citation
\usepackage{cite}
\bibliographystyle{ieeetr}
% change heading of bibliography
\addto\captionsgerman{%
  \renewcommand{\refname}{Literaturverzeichnis}
  \fancyhead{MyHead}}

% blind text for mwe
\usepackage{blindtext}


\begin{document}

\begin{multicols}{4}
\section*{Test}
\blindtext
Test \cite{wiki:test}
\blindtext

\bibliography{references}

\end{multicols}

\end{document}
