Safe to ignore no-HTTPS-nag on a local NC install?


Question first, details below: On my local NC install, is it safe for me to ignore the message on the admin interface nagging me that I’m not running NC over HTTPS or should I implement an self-signed certificate for NC?

I’ve installed Nextcloud (+ LAMP stack) in a VM on my own (on-premise) server and I haven’t made up my mind yet whether it will only be accessible on LAN + VPN or if I will expose it to the internet through my Traefik2 reverse-proxy (with LE cert.).

Nevertheless, Nextcloud will never be directly exposed to the internet.

Nextcloud and the host communicates via a bridged network interface.

Thanks in advance for your advice!
