SOLVED - Zero Touch Configuration - Provisioning with HTTP(s) Authentication

Under port management I have the following configuration:

Service Insecure port Secure port
admin 80 443
UCP 81 4443
HTTP Provisioning 83 1443
RESTful API 85 2443
RESTful Apps 84 3443

Under provisioning protocols I have:
FTP disabled
TFTP disabled
HTTP(s) Authentication Both

Under Endpoint Manager template I have the provisioning address as https://username:password@FQDN:1443
On the Sangoma Portal I have the following Zero Touch config:
Redirection Type: IP/FQDN
IP/FQDN Protocol: https://
IP/FQDN address: username:password@FQDN:1443

If I change the https to http and the port to 83 the phones provision. When set to https and port 1443 the phones never pickup a config.

Am I missing something?
Is there a way to debug this? I do not see any error messages on the phones.

Thank you for your support.
