PBIRS behind nginx

[Anonymous]

I need to place PBIRS behind nginx for policy reasons, and I seem to be getting 401/400s. I followed the directions for putting it behind an NLB (the only concrete step I took was to create the BackConnectionHostNames key, and add `localhost` and the hostname of the machine to it), but it still doesn't work (fast fail to 401/400, if I attempt to use 127.0.0.1 I can get a login prompt that I can't pass).

I don't see more detailed logs about these requests (not in the PBIRS logs, and not in the Event Viewer).

How can I fix this?

Hello Soandos,

Were you able to make Report Server work with nginx?

I need to do the same thing and for me only the authentication screen appears after that the error 400 appears.

The issue was that nginx (the free version) cannot forward NTLM authentication (technically this is because NTLM authentication happens for a session, not for a request).

We ended up having to use IIS with custom scripts to do what we wanted to do

Sorry I could not be of more help
