I encountered this issue as well when using the wireless adapter. I switched to direct cable network connection to the router/switch but the issue persisted. I was able to identify that the security settings on the studio firfewall were preventing a successful connection to the Eventide server. I moved the H9000 IP address to the DMZ on the network router and voila it connected to the Eventide server with no error message. I suppose there are possibly a few firewall ports that need to be allowed for successful connection of studio devices to outside servers. If the list of ports/protocols that need to be enabled or open on the firewall (other tha standar 80/HTTP) were listed, one could update the security profile on the router to permit connectivity accordingly eliminating need for a DMZ port to be setup for th H9000.
