Too many bots on my forum

[Niiicu]

Hello,

Someone threatened me 10 minutes ago that if I don't pay him 100e in BTC, he will make my forum to fail 24/24 hours.
I told him to go away, but I see that now the forum doesn't work anymore, the page practically doesn't load.
I can see so many visitators, i think that's the problem.
How can i fix this?

Thanks,

Is IP root is the same for all guests ?

I don't know where i can check it because now my forum it's down.

The server is temporarily busy, try again later!

Contact your host and ask them if there is any DDoS protection which can be enabled.

You do not use CloudFlare i guess ?

No, i don't have yet.

I contacted the host and they told me to add my domain on Cloudfare and to activate Under-Attack Mode on Cloudfare and after to send them a new ticket.

Hello,
I have Cloudfare now, but i also have the same problem.
It seems that Cloudfare can't block this

Did you activated under-attack mode ?

Did you activated under-attack mode ?

Yes, but is not working

Did your host change your IP? If the attacker still has it, CloudFlare doesn't matter.
