It show me front-end web page with page not found error.

i was having the same issue...this helped me fix the issue: https://wordpress.org/support/topic/plugin-yoast-google-analytics-save-settings-page-not-found

i too contacted my web host provider...they white-listed a rule that was causing the issue...i was able to authenticate successfully w/out having the page not found error pop up.

Thanks for @one50mph that is how I fix the problem.

Thank you, @one50mph! My hosting provider solved the problem.
