Just to inform you, I stumbled across this little issue.
When you change the password for the SSH user in the Network Settings, the credential in the Network Settings is username + new password. However, the credential saved in the Shared Device Setting of the devices is still username + old password.
This means you have to proceed like this:
- Before changing the password you need to create a Device Group containing all devices using the specific credentials.
- Change the password.
- Open the Shared Device Settings of one of the devices and reapply the user to the device AND the Device Group.
When you did not create the Device Group before changing the password, that Device Group will be empty.
