Unable to create Slice, Errors at all ticketed nodes

Hi all,

I have been working on an experiment for the last three months where I submit a slice when I start working on it, and delete the slice when I am done for the day. I haven’t changed anything about the code, but since a few days my slice won’t stabilize because of a “failed lease update” error (screenshot in the attachment) on every ticketed node.
How can I fix this?

The code used to create:

from ipaddress import ip_address, IPv4Address, IPv6Address, IPv4Network, IPv6Network
import ipaddress
from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager

fablib = fablib_manager()

fablib.show_config();

slice_name=”Experiment Slice”
node1_name=”Node1″
node2_name=”Node2″
# This will be the router node
node3_name=”SR-ingress-node”
node4_name=”Source-Node”
node5_name=”Destination-Node”
network_name=’net1′
node_location = “AMST”
image=”default_ubuntu_22″

# Create a slice
slice = fablib.new_slice(name=slice_name)

# Network
net1 = slice.add_l2network(name=network_name, subnet=IPv6Network(“2001:0db8:85a3::/64”))

# Add a node
node1 = slice.add_node(name=node1_name, site=node_location, image=image)
iface1 = node1.add_component(model=’NIC_Basic’, name=’nic1′).get_interfaces()[0]
iface1.set_mode(‘auto’)
net1.add_interface(iface1)

node2 = slice.add_node(name=node2_name, site=node_location, image=image)
iface2 = node2.add_component(model=’NIC_Basic’, name=’nic1′).get_interfaces()[0]
iface2.set_mode(‘auto’)
net1.add_interface(iface2)

node3 = slice.add_node(name=node3_name, site=node_location, image=image)
iface3 = node3.add_component(model=’NIC_Basic’, name=’nic1′).get_interfaces()[0]
iface3.set_mode(‘auto’)
net1.add_interface(iface3)

node4 = slice.add_node(name=node4_name, site=node_location, image=image)
iface4 = node4.add_component(model=’NIC_Basic’, name=’nic1′).get_interfaces()[0]
iface4.set_mode(‘auto’)
net1.add_interface(iface4)

node5 = slice.add_node(name=node5_name, site=node_location, image=image)
iface5 = node5.add_component(model=’NIC_Basic’, name=’nic1′).get_interfaces()[0]
iface5.set_mode(‘auto’)
net1.add_interface(iface5)

# Submit the slice
slice.submit();

Thanks!
