A TED reply was received that does not match a TED probe that is pending. This condition may be a one-time occurrence due to a delay of the the TED reply or ill-formed packets sent by the peer. This condition might be considered a hostile event.

It could be keepalive problem : try this

going to %System Root%\Program Files\Cisco Systems\VPN Client\Profiles on the Client PC that experiences the issue, and edit the PCF file (where applicable) for the connection.

Change the 'ForceKeepAlives=0' (default) to 'ForceKeepAlives=1'.

what version of VPN client you are using?

Try this:

Hi Muhammed,

You might also want to try this :

1. Modify the connection entry in the VPN client.

2. Goto Transport tab.

3. Set the 'Peer Response Timeout' to 480. Default is 90.
