Hello!
I want to set up a proxy for Exchange Server 2016.
I can’t understand why NGINX doesn’t send authentication data.
Help me figure it out, please.

When I try to authenticate I get the error:
2023/10/31 10:23:52 [error] 5315#5315: *15836 auth http server 127.0.0.1:80 did not send server or port while in http auth state, client: 1.2.3.4, server: 0.0.0.0:143, login: "user@domain.com"
