  1. Cannot login to Power Panel, the error is shown : invalid username or password

  2. Power Panel for other containers on the same hardware node works fine.

  3. I can login to the container via SSH with the same username and password.


One of the possible causes is that the same IP address is used by another container in the network.


Check that the IP address is not used by any other container on other servers.

This can be confirmed with tracing the route to the container, the last hop should be the hardware node's IP address (if the container is in host-routed mode) :

    ~# traceroute <ip_address>

Once the node is identified, list all containers with their IPs and find the needed one :

    ~# vzlist -ao veid,ip | grep <ip_address>
