We can't connect the client to the server, shows that it never connected.

Hey, we're trying to connect our Windows servers to OSSEC.
It works for some of them, as for others it isn't.

The error:  ERROR: Incorrectly formatted message from

We used the correct key, as it works on some servers.

We tried these links:

https://www.ossec.net/docs/faq/unexpected.html#the-communication-between-my-agent-and-the-server-is-not-working-what-to-do    

How does it work here?
Who do we talk to and can anyone help?

Are each of the keys installed on each server unique? They need to be unique.
Are the packets from the rejected servers coming from the correct IP
addresses (you can use tcpdump on the ossec server to make sure)?
