"Server is offline" error ​
This error indicates that something is wrong when our nodes try to reach your backend. While we do provide assistance with resolving this, this site should be self-explanatory and should help you to resolve these issues completely.
Checklist: ​
1. Check proxy protocol ​
Make sure to have set ALL config options we listed here and to have proxy protocol turned on in our panel.
2. Check if you entered the right backend ip:port ​
Just re-check if this was the right backend ip and port you connected with before.
You might use the command ss -tulpn
on linux servers to see if the port is open on your machine.
3. Check your firewall for firewalled ports ​
You most likely know how to do that as you must have set it up in advance.
Here are a few commands to help you check your linux firewall:
ufw status
iptables -S
iptables -t raw -S
4. Check for other interfering plugins ​
Please check if you have any plugins still installed from other protection provider you may were previously.
Also: You might want to check if any antibot blocks connections or rate limits them. (That can also be caused by bungee forks)
5. Check for your hosters protection ​
There are a few hosters out there that have their own ddos protection and they cause issues due to blocking traffic coming from neo.
This is as all your traffic comes from only a few IPs (which would to them most likely appear suspicious)
