Question about SSL on the API service in TrueNAS Scale 25.04

TrueNAS General
1

I recently upgraded from 24.04 to 25.04, and it went well. I have a proxmox cluster connecting to truenas over iSCSI for my storage. Following the upgrade, when I attempt to do a disk migration, I’m getting the following error:

Header
Virtual Environment 8.4.1
Logs
TASK ERROR: Unable to connect to the FreeNAS API service at ‘10.7.2.60’ using the ‘https’ protocol at /usr/share/perl5/PVE/Storage/LunCmd/FreeNAS.pm line 380.

This makes sense; I do have a CA signed cert on my truenas, however it’s for the FQDN and the web IP, not the API/storage network IP. On the proxmox side, the iSCSI connector is configured to NOT use SSL for the API connection:

I’ve been searching, but my question is, is a change to TrueNAS redirecting the API connection to require ssl now? If that is the case, can I disable that, rather than re-issue the cert?

Additionally, I’m tracking this issue in the repo for the zfs over iscsi plugin, but I think the https response is pretty specific: Truenas Scale 2025.04 api error · Issue #205 · TheGrandWazoo/freenas-proxmox · GitHub

Thanks!

There are two issues: First, that as of 25.04, the HTTP API is gone and replaced with a websocket one; second, again as of 25.04, you cannot submit API keys over an unencrypted channel–the system will revoke any keys submitted that way.
