Error on using external API in GPT

i added an action to my GPT.
when i call the API from postman or browser i get answer.
when the GPT try to call the api i get “Error talking to”

i dont see any events in my server log but i see events when i use postman
the api is simple and always return data

The “Error talking to” message suggests that the custom GPT is trying to access an incorrect URI.

Please ensure that the action you set up points to an endpoint with SSL/TLS and that the OpenAPI schema is correctly configured.

The below are URLs for your reference:

You can ask ActionGPT if the schema is correct:

Also, make sure that your instructions specify using the correct action.
