Overfull problem with an url
Add option hyphens
to package url
to allow breaks at explicit hyphens in URLs:
\usepackage[hyphens]{url}
With more breakpoints, it is easier for TeX to break paragraphs into lines without overfull \hbox
es.
Using xurl
package instead of url
(see here):
\documentclass[12pt,twoside]{report}
\usepackage[headheight=18pt,a4paper,width=150mm, top=25mm, bottom=25mm, bindingoffset=6mm]{geometry}
\usepackage[utf8]{inputenc}
\usepackage{fancyhdr}
\pagestyle{fancy}
\setlength\parskip{1em plus 10pt}
\renewcommand{\headrulewidth}{0.4pt}
\renewcommand{\footrulewidth}{0.4pt}
\usepackage{xurl}
