How to configure Nifi behind a load balancer with OpenID connect authentication?

[#1]

I have a Nifi instance behind an AWS Elastic Load Balancer. The OpenID provider (AWS Cognito) is complaining that the redirect URI s invalid. I presume the OpenID provider wants to post to the underlying node name instead of the public domain name used for the UI.

How to I tell Nifi to post to the load balancer instead of the underlying node name? I have already tried setting the proxy host name in nifi.properties but that doesn't work.

Thanks!

Solved: Specify the load balancer port in the OpenID callback url. For example:
