Why don't rules work in .htaccess (how to compose RewriteRule )?

Question

Yii

Yii2: There is a FlightsApiController->actionSearchFlights()
.htaccess controller:

RewriteRule ^([^/].*)?$ /app/frontend/web/$1 [L,PT]

domain.ru works
domain.ru/flightsapi/search-flights doesn't work
The funny thing is that everything works as it should on LAN.

Answer 1

Understood, you need to request the controller asflights-api

Answer 2

Once again, users can hardly tell the difference between a local web server configuration file and a specific module configuration problem.
From here we see a question that contradicts its name: by the title, we will rightly decide that no directives work at all because of AllowOverride, and in the body there will be a question on compiling rules for mod-rewrite.
