Plugin Setup Error with POST API Call

I receive the following error when I try to configure a API Plugin. This is a POST request.

**There was an issue setting up your call. **

**Raw error for the API **
{“code”:“UNABLE_TO_VERIFY_LEAF_SIGNATURE”}

With the URL of the following format:
https://xxx-xxx.com/ara-web/services/engine/v2/XXX/xx

However it works with the below URL which is the initial draft version.
http://xxx-xxx.com/ara-web/services/engine/XXX/xx

Are there any limitations on the URL in Bubble…

that usually means there is an issue with the urls signature… so, if you want to use the https not that it will really help while the signature has issues the you should be able to add rejectUnauthorized: false to your call.

Solved: Thanks for the pointer. Changing from https to http solved the issue.
