Nginx reverse proxy with Sharepoint web

[blason]

Hi Guys,

I am kindaa facing an issue with sharepoint sub-sites authentication with
nginx as a reverse proxy. Somehow primary site is perfectly getting
authenticated with upstream and ntlm however subsites shows 401 and 404
error.

Does anyone have any use case or working configuration with sharepoint and
nginx as reverse proxy?

Thanks and Regards,
Blason
