you answered own question in comments, stumbles upon this;

you should load wordpress stylesheets , js files "the wordpress way" noted in theme handbook

wordpress uses custom routing requires load stylesheets theme directory. rather trying use relative url /style.css or style.css follow guide linked above , use wp_enqueue_style() function either get_stylesheet_uri(); or get_template_directory_uri(); locate file.

edit: note not 2 functions can used locate stylesheet. noted above can use get_bloginfo() or bloginfo() functions , pass 1 of many parameters accepts. read in codex.
