You configured `modeconfig=push`, so strongSwan pushed config attributes
to the client and waits for a response.  If that's not what the client
expects change the config to `modeconfig=pull` so the client is expected
to be the one requesting the attributes.

Obviously, the two peers don't agree on the mode to be used.

No, a misconfiguration.
