So I don’t give up easily. I ended up finding this solution which worked for me. Editing the config.php apparently is ignored by NC… Adding Environment Variables to the App installer resolved it for me.
- removed entry in “Host”
- added “Additional Environment Variable” OVERWRITEHOST with Value 192.168.178.28:30027
- added “Additional Environment Variable” OVERWRITECLIURL with Value https://192.168.178.28:30027
- set Certificate ID to use the freenas_default Certificate.
192.168.178.28 is the IP address of my Truenas scale installation. 30027 is the port I’ve also set in WebUI Port.
Hope this helps someone else.
