Default [HELP] Query Attack

Hello,

I am having a serious problem for two days. My server appears offline in the samp client, but users can connect and play perfectly (without lag or anything).

My server is usually attacked with DDOS once a week (and my antiDDos responds well), so this maybe an attack too
I checked the server log (600mb in 2 hours), and there is masive connections (query attack)

Code:
[11:34:58] [query:i] from 186.126.175.156

[11:34:59] [query:i] from 181.54.210.186
My provider is OVH US, and I haven't had any problem before this.


It is a serious problem, because users think they are offline and do not log in. We lost 50% of them

Can someone help my?

Thanks in advance

You should contact OVH support regarding this. They provide good customer service and they're the ones who can help you with this.

I opened a OVH ticket yesterday, waiting for them to answer me.

I'm using provisionally samp-packet-proxy and the problem has gone. If somenone have the same attack, try it

You can use CSF firewall in order to limit querying to those ports which may cause a huge lag on your server side to clients.
