New instalation from source got 404

Question

I try to install taiga from source. All component including rabbitMQ and PGSQL in a single VM. I want taiga accessed as sub-path, with access scheme http.
Installation/Configuration steps

VP IP is 192.168.1.70 and my station is at 192.168.12.26.

When I try to access http://192.168.1.70/taiga/api/v1/, JSON is showed like expected.
But when I try to access http://192.168.1.70/taiga or http://192.168.1.70/taiga/ I got HTTP 404

Here is some of my configuration
