SSL/TLS error when using invoke web service action
We are having issues when invoking web service. When sending a request, we get an error form WinAutomation "Runtime Error: Failed to invoke web service: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.". When trying to access API via web browser there is a message notifying that "The site is not secure". Now we do know that we are working with a trustworthy API. Is there any way to work around the issue and bypass the error?
Thank you in advance!
