Comment 8 for bug 1705508

Can you post the logs of the rack controller this is happening on? http://127.0.0.1:5240/ is the default value when the maas_url isn't found in the config file which is why I thought the two might of been related.

While trying to debug this issue I came across lp:1705774, reverting 48efa8062b866c9b1b82fdca6be2c0e7067e472e solved the issue for me, I'm wondering if that commit is causing this error as well.
