core: Nextcloud error: "local variable 'ncm' referenced before assignment"

The problem

After adding nextcloud integration to my configuration.yaml file, I keep on getting a “Please check your config.” error notification.

Environment

Home Assistant Core release with the issue: HA 0.108.5. Same behaviour on previous versions (0.108.1 to 0.108.5)
Operating environment (Home Assistant/Supervised/Docker/venv): Hassio installed on a Raspberry. Nextcloud is hosted on another Raspberry on the same network, running LibreElec with Docker, Nextcloud being a Docker container.
Integration causing this issue: Nextcloud
Link to integration documentation on our website: https://www.home-assistant.io/integrations/nextcloud

Problem-relevant `configuration.yaml`

nextcloud: url: https://192.168.1.250 username: !secret nextcloud_username password: !secret nextcloud_password

Nextcloud is running well on the above IP. I have generated the paswword in Nextcloud Web UI as instructed.

Traceback/Error logs

Hi, After a few days trying to understand how to use Letsencrypt on my server, I did it and I have now access to Nextcloud from Home Assistant! Thank you

@Alomon31 Yes, LetsEncrypt would be the best solution. As the developer mentioned, using a reverse proxy is the best idea. If you have access to the home-assistant addons, you could use the NginxProxyManager to handle all the Let’s Encrypt certificates.

scan_interval didn’t help. The error message shows up as soon as HA server starts up. I close the issue as requested.
