We recently migrated our Windows servers to a new provider. So, the IP address changed in our Cisco ASA 5505. After setting up the Spark IM client in one of our branch offices in SC, I can't contact the Spark server running on our production server. At least we can't connect from SC. We can connect form our OK office and various remote PCs. I can ping the server from inside the SC network. Spark is using port 5222. When I try to log in to Spark from an SC computer I get the error message "Can't connect to the server. Invalid name or server is not reachable".
