1980	custom 401 error_page with auth_basic never shows the custom 401 page	mmattel@…		"When using auth_basic (works great) and defining a custom 401 error page, the custom error page is never shown, only the default nginx version.
auth_basic and error_page are in the serverblock, no other 401 error pages defined somewhere else. Imho when pressing cancel on authentication, the custom 401 page should be shown, not the default one. The location =/401.html has auth_basic_off; as directive included.

Everything fine with nginx -t

Seached the internet without success.
