RESTful notification - login error

I have scourged google trying to resolve the login error for the rest notification I receive.

Client error. Response 401: Unauthorized:
NoneType: None

The shell command works as it should. Home Assistant has the addon NGinx HA Proxy which uses the default config and is working properly. The rest notify is configured as:

HA config has for HTTP:
http:
use_x_forwarded_for: true
trusted_proxies:
- 172.30.33.0/24
- 127.0.0.1
- ::1

The HA is a VM on Proxmox. Any suggestions/hints on how to resolve this is appreciated.
