A newb question on Web Interface HTTP → HTTPS Redirect

I’m a complete newb with TrueNAS. I try to follow good guides on setting and protecting my NAS. Here - TrueNAS Hardening Guide 2026 - Cyber Security & Hacking - Lawrence Systems Forums listed ways on how to increase the security of one’s NAS. Among them is

  • HTTP to HTTPS Redirect:

    • Menu: System > General Setting > GUI

    • Ensure “Web Interface HTTP → HTTPS Redirect” is enabled so all management traffic is encrypted.

As I understand for HTTPS to work one needs SSL certificate and there is one self-issued by TrueNAS upon install (can be seen under Creditinals > Certificates), so two (maybe naive) questions:

  1. if I check Web Interface HTTP → HTTPS Redirect - will I be able to login? Should I ‘confirm’ self-published certificates on my devices (currently only my PC) first?
  2. SSL certificates are issued for one year - can there be any problems in a year, when it expires?

Can you log in currently using HTTPS on all your devices? That would verify it.

Thanks, a simple solution but I haven’t thought about it - yes, there should be HTTPS working even now! What about expiring certificates?

update: Chrome says net::ERR_CERT_AUTHORITY_INVALID but that’s because it is self-issued I presume, so I just proceed

Yes, that would be the reason for that error. You’ll get a different error when the cert expires, but you should be able to bypass it in the same way.

You can add trusted certs to your system in a few ways. One is to register for TrueNAS Connect, which takes care of it for you. Others are discussed here:
