Cannot connect to GUI after installing minio

I have recently installed TrueNAS Scale 24.10.0.02 for testing purposes on a Hyper-V VM (with nested virtualisation enabled). I have domain joined, set up a CIFS share and provisioned iSCSI block storage without issues, however when I installed minio, I lose GUI access. When trying to connect to the GUI IP in a browser I see the message " Connecting to TrueNAS … Make sure the TrueNAS system is powered on and connected to the network. ".

The TrueNAS system is alive, I can log in to the CLI. iSCSI block storage is also alive, but my CIFS share is down.

I have tried installing minio with all sorts of variables, certificates, etc. but it always results in the same problem. Is this something related to me running TrueNAS in a virtualised environment or am I doing something wrong with the minio installation?

Happy to provide whatever info or dumps deemed necessary.

The Hyper-V instance has 4x vCPUs, 32GB RAM, 2x 120GB SSDs for OS, 1x 120GB SSD for cache, and 8x 160GB HDD (1x 6-wide RAIDZ1 and 1x mirror Pools). It also has 2x NICs assigned, one for production network access (172.16.0.0/16) and one for iscsi (192.168.0.0/24).

Any light that can be shed on this would be greatly appreciated.

Thanks.

After some more testing, I can in fact connect to the GUI using the iSCSI IP.
My production NIC is eth0, and iSCSI is eth1.
Eth0 seems to be the issue, and even resetting the IP address settings doesn’t seem to help.
When logging in to the GUI, I can try to start minio, but it tries to start a number of times and fails.
Any suggestions on why eth0 may not be working properly?
