Cannot run it on a server

dear all,
I am totally new on dash.
And i am trying to install and run the test codes.
when i run the test on a local mode, it did work, however, when i am trying to use a server with apache.
it failed as showing “Loading…” without changing the page.

I made the proxy to shift a folder as:8050.

ProxyPass /test_dash/ http://localhost:8050/
ProxyPassReverse /test_dash/ http://localhost:8050/

Chrome tells me the “hogehogehoge/_dash-component-suites/hogehoge” was Forbidden.

Surely, there is no /_dash-component-suites/ in the folder, did i miss something? where is the /_dash-component-suites/? can anybody write me a help?
