Custom Connector: Was working in PA, works outside of PA, but stopped working inside PA.

Hi All:


I created two custom connectors for our organization that sends API requests for validation purposes.

When I created them in 2019 they were working without issue and processed thousands of requests.


Since the pandemic, the flows where not run.


As we are starting operations back up, I went to check the flows and noticed that the custome connectors stopped working within Power Automate. 


When testing the connector I get the errors shown below.

When I test via URL and Postman I get the successful response back.


Has something changed with the connectors that breaks backwards compatibility?


Any ideas/suggestions would be appreciated.
