Login authentication failed error on remote upgrade


We cannot upgrade several PMP450's due to the following error, appearing in the latest CNUT:

Host: x.x.x.x; ESN: bla; Message: Login authentication failed,org.apache.http.conn.HttpHostConnectException: Connection to https://PMP-IP refused (SITE = PMP-HOSTNAME)

We are trying to complete our rollout today, but this error is appearing on 5% of our cambium devices.

Any ideas?



We have discovered the admin account has been left as default on a small percentage of devices. Changing the admin/password fixed the issue.

Perhaps, having a simple 'Username/password incorrect' message in CNUT would lead to less confusion.
