A connection check error occurred due to a App:communication Arrangements

[TaiseiTakaki]

I am customizing an extensibility app with reference to the article below.

After configuring communication management, an error occurs when I press the communication check in the "Communication Contract" app, and I cannot proceed with the verification.

error1: The ping of the outbound service has failed

error2: 403 Unified Connectivity: Forbidden

Please let me know the cause of the error and how to avoid it.
Kind regards.

I have posted screenshots of the communication system/scenario/contract I have set up.
I would appreciate it if you could take a look.

Hello Taisei, I think the cause is that the service is not following after the url "http....sap". This document also helps you to understand the whole procedure of creating custom communication scenario→https://community.sap.com/t5/enterprise-resource-planning-blogs-by-sap/part-viii-custom-business-obj...　Thanks&Regards,
