Remember kids.. this thing is a server. Your clients have to be able to see it.
After testing, we found this thing wouldn't work without both TCP & UDP opened in firewall. So 8881 needs to be open.
Another thing I found (as I run my servers behind nat).. host *had* to be filled out to be my external IP (same as SeamlessIP).
So remember to
- If you need (nat), add external IP to the Host option in config.
- Open it in firewall
- If needed, forward the port (your players have to be able to hit it)
- Ensure it can access your redis.
