Hello

We have a process flow where we want to check if an user_id exists in IAM.

In order to do this we created a Web Connection with the proper Endpoint, however it didn't go as planned because even if in Postman the calls (with the same user & pass) are working

When we try with Web Connection or Http Connector, it is failing with status -23 (web connection) and -7 (http connector) and the following error on error log

In the past we identified that Postman was auto-calculating the "Host” header on the call, we solved the issue by explicitly provide it in the headers, but now seems that is not enough.

Did you encountered this or have any idea how we can solve this issue?
