RIP, this will be hard......

[DarkWav]

OK I think i figured out the problem. I think I now got an actual fix, not just a borked workaround like in patch 1. Try patch-2: API 3.0.0 | API 4.0.0

[teracube]

@DarkWav I tried patch-2: API 3.0.0 and i have same error

[HiddenMotives]

Is this only when you use subnet banning or does this also occur when someone connects with a VPN and is kicked?

[teracube]

@HiddenMotives this concerns only 1 player in a week, a same player that his ip is subnet banned in banned.yml files on line 124 124: 88.XXX.XXX.220/32 json files { "status": "success", "package": "Basic", "ipaddress": "88.XXX.XXX.220", "host-ip": false, "org": "PROXAD" }

ip 88.XXX.XXX.220 is not a vpn

no others player is concerned at the moment

sorry for my bad english

[teracube]

@HiddenMotives @DarkWav
