I click html button to another url everything is fine, browser url location is changed right but when if click the browser reload button it's show a 404 page, browser url diden't change.

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback. Thu Feb 01 11:34:25 UTC 2018 There was an unexpected error (type=Not Found, status=404). No message available
