How to publish via nginx sharepoint with basic authentification?

Question

SharePoint

Good afternoon. I'm trying to publish sharepoint via nginx. On sharepoint basic auth. There is a repeated request for authentication, endlessly. Rebuilt nginx, added ngx_http_headers_more_filter_module (to use more_set_input_headers). To no avail. Config below.
Thanks in advance.
