I want to clarify, do you have access to that endpoint that you are trying to connect to? Have you tried connecting to that endpoint using postman to make sure you can connect to that endpoint? Also, which endpoint are you trying to connect to exactly?
I have a access to API end point and I can able to connect through postman also.
I have a case when there is some server down then I will get 500 error code from API. In these cases from Skuid it will return an error " Please contact your administrator" in red colored banner. Instead of this generic error message i want to display some custom error.
I just confirmed on my end, and you would still have to check with the third-party service to see if you can change the message on their end since Skuid does not return: Please contact your administrator as a custom label.
As of now, the only way you can do it, is by coding it in to change the return message.
