[SOLVED] Failure backing up LXC - "Method 'GET /nodes/TracheNodeA/vzdump/defaults' not implemented (501)"

[jsalas424]

I recently restored this LXC container, and now I cannot back it up. I am able to backup VMs to this same directory in the same job, just cannot backup the LXC.

Method 'GET /nodes/TracheNodeA/vzdump/defaults' not implemented (501)
