Core: Smartthings token not accepted due to base_url

[mike1237]

Home Assistant release with the issue:
94.X

Last working Home Assistant release (if known):
93.1

Operating environment (Hass.io/Docker/Windows/etc.):
HassOS x86 image on Hyper-V

Component/platform:
Smartthings integration

Description of problem:
I am a Nabu Casa subscriber and was using the built-in webhook functionality working with the smartthings integration to connect Hass.io and Smartthings without exposing my Hass.io directly to the internet on v93.
In v94, when attempting to add my smartthings token code as per the instructions, I get the below error:

The base_url for the http component must be configured and start with https://

This occurs even from the new setup wizard when trying to add smartthings.
I assumed this first occurred here because I had not logged into NabuCasa.

After logging into Home Assistant Cloud and ensuring webhooks and remote access were enabled, the issue persists.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):
Default config - it is commented out and I believe unrelated.

# Uncomment this if you are using SSL/TLS, running in Docker container, etc.
# http:
#   base_url: example.duckdns.org:8123

Traceback (if applicable):

Additional information:
A couple of forum users have experienced the same issue, even after adding base_url, and seemingly without relying on Home Assistant Cloud.

When you are logged into Nabu Casa with a non-expired account, base_url is not even used or checked by the SmartThings integration, so it's not being picked up. Are you sure the account is active? If so, remove SmartThings, restart, and after ensuring it's showing logged in, try setting up the integration again.

The linked forum posts and error logs are not the same issue.

I'm going to close this issue for now given there's been no response in over a month.

[zaileion]

can it be re-opened, cause i getting the same error when i try to add my token..

[massimopetrossi]

The same error here: in Italian is

Il base_url per il componente http deve essere configurato e deve iniziare con https://.

but... which base_url? there're no url in API Token!
What does it mean?
