Instead of Lynx to recursively check for broken website links, use wget website broken link checking.
lynx text web browser had a built-in facility for recursively checking websites for broken links by
lynx -traversal https://www.scivision.co

lynx: Start file could not be found or is not text/html or text/plain Exiting…
as a result, one resorts to wget website broken link checking
