The connection is working fine.
I suspect the issue is the hostname of vseServer - mentioned as {server} in your comment above - cannot be resolved when connected via Mac over intranet wifi.
I can think of two ways to resolve this. Either
1. Add an entry in your /etc/hosts file
xxxxxxxxxx {server}
where xxxxxxxxxx is the IP & {server} is the hostname from your comment above
Or
2. Configure the VSE service to be named as tcp://xxxxxxxxxx:2013/VSEName & restart the VSE process
