@everybear, @genweb thanks for the help so far.
If I visit /wc-auth/v1/authorize, I get the not found page.
I have the permalinks set correctly. and I am running a server with centos 7. I installed wordpress at another server, a sandbox I use for experimenting and the same thing is happening.
160.119.69.69/wp-login.php
username:admin
password:password
even on the server, there’s no file called /wc-auth/v1/authorize
Is there a way I can just make that page and put it there?
