Invalid Peer ID

[soph one]

Hello,

I am using the seaf-cli to sync with my server.. Now, when I execute the sync command it returns:
"pysearpc.common.SearpcError: Invalid peer id"

The same client used in other PC synchronizes well.

My ccnet.conf is located in: /etc/ and it contains the following :

[General]
USER_NAME = anonymous
ID = 28c1dc9a484251ae23b663a6fc1ba3f55d25c576
NAME = anonymous

[Client]
PORT = 13419

What is the problem ?

Thanks
