Channel Settlement Problem

[msaxena18]

I am trying to transfer some tokens between two MetaMask accounts. I am currently using the Client code from the uraiden example that looks like:

from microraiden import Client

receiver = '0xb6b79519c91edbb5a0fc95f190741ad0c4b1bb4d'
privkey = '0x55e58f57ec2177ea681ee461c6d2740060fd03109036e7e6b26dcf0d16a28169'

with Client(privkey) as client:

channel = client.get_suitable_channel(receiver, 10)
channel.create_transfer(3)
channel.create_transfer(4)

print(
    'Current balance proof:\n'
    'From: {}\n'
    'To: {}\n'
    'Channel opened at block: #{}\n'  # used to uniquely identify this channel
    'Balance: {}\n'                   # total: 7
    'Signature: {}\n'                 # valid signature for a balance of 7 on this channel
    .format(
        channel.sender, channel.receiver, channel.block, channel.balance, channel.balance_sig
    )
)

channel.topup(5)                      # total deposit: 15

channel.create_transfer(5)            # total balance: 12

channel.close()

# Wait for settlement period to end.

channel.settle()

The error I get is: 500 more blocks until this channel can be settled. Aborting.

How do I fix this issue? Thanks!
