blank page when running oauth2ms

[dellplayer]

I followed all step in azure app setup and config.json.
When I run oauth2ms, it connects to microsoft login page, I login and accept to give authorization to page. Then it displays a blank page. I don't have the authorization successful text.

When I reload the page with web developper tools enabled, I get a 403 error

What am I missing?

If you are using a mac and used port 5000, this post might help.

It works!
I had to use port 5001 (some ports are blocked by macos so you cannot use any port).
Thank you so much!!!
