This article describes a condition where an SSR device remains connected to the Mist Cloud after an upgrade, but the Mist portal is unable to display the last known configuration status for the device. The article also provides a workaround to address this condition.

1) The 128T Mist Agent logs indicate that the device is unable to download the required package. This can be verified by checking the Mist Agent service logs using the following command:

journalctl -u 128T-mist-agent -f

Sample: 

2) The repository list for the 128T software may display the status “Unknown” under the Credentials column. This can be verified by running the following command on the device:
install128t repo list

Sample: 

3) Network latency caused a download failure, preventing the SSR device from retrieving the required software package.

Step 1: Resolve authentication failure for 128T repositories

Run the following commands to re-authenticate and enable the required repositories:

install128t repo authenticate -u <username> -t <password>
install128t repo enable alpha beta
dnf clean all
install128t repo list

Note: Replace <username> and <password> with the appropriate credentials.

Step 2: Verify network latency

To validate network connectivity and latency, run the following command to download a test file. Delete the file after the test completes.
