Hi,
You have to thoroughly check port numbers added to the config-file of your client.
E.g. Your client has VIP-lalala subscription. It includes the following ports:
10001
10002
10003
10004
But in newcamd.list (for example), there are the following ports added:
10001
10002
10003
10005
The port 10005 is not valid for this subscription, but it is valid for other subscription (VIP-blablabla). That is why you receive this message.
I am sure, one port in your client's newcamd.list (or whatever where port numbers are added) is extra and it is not included in the subscription available.
