deployment occasionally breaks with this error: 401 UNAUTHORIZED Nonce already used

[David Britton]

This happens periodically, but is very annoying when it does, since juju doesn't seem to retry it, and I can't do anything to fix it other than destroying the node. Back 6 months ago when I was using an older version of MAAS, I would get this Nonce error showing up during random juju

This is maas/juju-core from the UCA:

Here is a log of my interaction
