502 - BAD GATEWAY
Anti-DDoS Filter cannot connect to protected host.
Most likely the firewall (CSF?) on protected host blocks filter IP addresses due to a large number of requests.
If you are the administrator, please disable the firewall or whitelist the filter IP's.
Please whitelist these IP within your local firewall:
184.108.40.206/26 220.127.116.11/26 18.104.22.168/26 22.214.171.124/26 126.96.36.199/26 188.8.131.52/26
Notice for SSH:
No NOT change the standard SSH port or you will be locked out in case of an attack.
IF you see an invalid SSL cert (DDOS protection) its caused by the L7 filter.
To have a valid SSL cert we just need the SSL key in .key format and the certificate.
We will update our DDoS systems with the provided information and the SSL socket will be valid.
