Unable to hit the Azure AD token API from APIGEE edge on-prem

[sagarsinghj]

HI Folks,

I am trying to use Azure AD for one of my integration project.

I have APIGEE 5 node on-prem setup done on AWS instances.

I am trying to hit the following API but getting 503 Error.

https://login.microsoftonline.com/{tenantID}/oauth2/v2.0/token

But, if I hit this via APIGEE trial account on APIGEE public cloud it works fine and returns a proper response.

Also, If I hit the above API using the CURL command on AWS terminal (apigee message processor node), this works fine and gives the expected response.

Any idea if this is the issue with APIGEE on-prem on AWS or we have to do any configuration on Azure AD?

I think you are saying that the MP cannot connect with that endpoint, from within an API Proxy. If I were diagnosing this, I would look in the system.log of the MP.  If the MP cannot connect to a target, there may be some pertinent information in there.

Also, maybe you could show your HTTPTargetConnection configuration for that AD endpoint. Do you have TLS configured, and if so what does it look like?
