Issue
When trying to access the GUI you may observe the following error,
Username or password is incorrect.Failed to parse server data.
Solution
This is due to a bug with VSE 6.5 R2. Which is caused by the Vyatta Appliance not having an interface named ‘eth0’ present.
To resolve this,
- Edit the file ’/config/config.boot’ via vi.
- Change one of your interfaces to eth0.
- And then reboot your device.
