Hi,
I can successfully send SMS via my https provider via webserver (so syntax is correct) but when I try via erpNEXT I receive the error below (with details changed as needed):
HTTPError: 418 Client Error: reauthentication required for url: https://sms.australianphone.com.au/sendsms.php?mobile=04xxxxxxx&message=Test+from+erpNEXT&password=mypassword&senderid=mydetails&user=frappe
The syntax is correct, however the https error code maps to "I’m a teapot’ so hopefully there is a more sensible explanation for this error message!
