Unable to get break lines in URLs for bibliography

I cannot get the URL address in a reference in my document to break. I looked at this question’s chosen answer URLs in bibliography: LaTeX not breaking line as expected and it did not work for me.

The citation at "14" hangs over the right edge of left column boundary

MWE:

tex file

documentclass[10pt,conference,letterpaper]{IEEEtran}
usepackage[hyphens]{url}
usepackage[hidelinks]{hyperref}
hypersetup{breaklinks=true}
urlstyle{same}
usepackage{cite}
%usepackage{parskip}
% commented for existing packages in cls
usepackage{amssymb}
usepackage{amsmath}
usepackage{mathtools}

Urlmuskip=0mu plus 21mu
bibliographystyle{IEEEtran}

bibliography{IEEEabrv,reference}

bib file entry not breaking

@Manual{nmonchart,
title={nmonchart},
author = "Griffiths, Nigel",
address={http://nmon.sourceforge.net/pmwiki.php?n=Site.Nmonchart},
}

I have to edit the link because of protocol

Screenshot of the paper currently

@Manual{nmonchart,
  title  = {nmonchart},
  author = "Griffiths, Nigel",
  url    = {http://nmon.sourceforge.net/pmwiki.php?n=Site.Nmonchart},
}

documentclass[10pt,conference,letterpaper]{IEEEtran}
%% (I simplified the preamble to make it truly minimal)

begin{filecontents}[overwrite]{mybib.bib}
@Manual{nmonchart,
  title  = {nmonchart},
  author = "Griffiths, Nigel",
  url    = {http://nmon.sourceforge.net/pmwiki.php?n=Site.Nmonchart},
}
end{filecontents}

usepackage{cite}
bibliographystyle{IEEEtran}

usepackage{xurl} % not usepackage{url}
urlstyle{same}
usepackage[hidelinks]{hyperref}
%Urlmuskip=0mu plus 21mu % not needed when using 'xurl' package
