fail to ask question

Hi
I installed wordpress using docker image wordpress:latest.
And then install anspress via  “From plugin installer”  according to https://anspress.net/resources/getting-started/installing-anspress/ .
And then added base page .

After that , whenever I click “ask  question” botton  (http://192.168.123.123/questions/ask/) ,
the URL response nothing , the response webpage is “empty”

Did I miss any other installtion steps?
Thank you !
