Failing do add proxmox_storage_iso

[staticdev]

I have a direct connection from my machine to the proxmox, both in same switch and can access normally via browser. But in a simple test to add proxmox_storage_iso I am getting on tofu apply different errors:

OpenTofu will perform the following actions:

  # proxmox_storage_iso.nixos_linux_iso_image will be created
  + resource "proxmox_storage_iso" "nixos_linux_iso_image" {
      + checksum           = "123"
      + checksum_algorithm = "sha-123"
      + filename           = "talos-linux-v1.8.2-qemu-guest-agent-amd64.iso"
      + id                 = (known after apply)
      + pve_node           = "node1"
      + storage            = "local"
      + url                = "https://factory.talos.dev/image/ce4c980550dd2ab1b17bbf2b08801c7eb59418eafe8f279833297925d67c7515/v1.8.2/nocloud-amd64.iso"
    }

Result:

Error: Post "https://proxmox-ip:8006/api2/json/nodes/saga/storage/local/upload": write tcp my-ip:52296->proxmox-ip:8006: write: broken pipe

│   with proxmox_storage_iso.nixos_linux_iso_image,
│   on iso_images.tf line 1, in resource "proxmox_storage_iso" "nixos_linux_iso_image":
│    1: resource "proxmox_storage_iso" "nixos_linux_iso_image" {

Then I try again and instead of broken pipe I get use of closed network connection. But there is no closed connection, I tried again and get broken pipe again and so on.
