Hi team,

running the latest version of proxmox. I need to change the ip address of a standalone install so I went on the gui and change the ip on the vmbr0 nic. Rebooted but could not login from the gui anymore. try google and realised had to change /etc/host file also which I did but still cant login. The error msg i am getting now is connection error 401 permission denied- invalid ticket.
I have tried to change the ip back from the interface file still nothing so put if back to th enew one again.

here is the interface config:

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
# If you want to manage part of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

iface eth2 inet manual

iface eth3 inet manual

iface eth4 inet manual

iface eth5 inet manual

auto bond0
