High CPU usage & service abuse
-
@doodlemania2 it's on a biz VPS and the abuse is severe enough to have used up 200+GB of disk space, which I need to track down now.
Backups have been failing, and who knows what else.

https://forum.cloudron.io/topic/3840/adguard-on-upcoming-cloudron-v6-ddos-reflection-amplification
And it's in the docs:
https://docs.cloudron.io/apps/adguard-home/#securing-installation
I think DDNS doesn't work because you have to add an IP in AdGuard, I have the same issue with my home connection, that's why I don't use AdGuard in my personal Cloudron. I run Pi-Hole in my home network on a Raspberry Pi.

@robi Does your VPS provider not let you block port 53? Or do you need it to be accessible externally?

@atrilahiji I might be wrong about this but I think port 53 needs to be used to resolve DNS, and since @robi mentioned that he installed it on a business VPS it has to be publicly accessible for it to function. If it were a homelab would this be less of an issue?

Thanks torcloneI uploaded all 222GB to my Google Drive in less then a couple hours. (didn't time it, but expected it to be much longer.)VPS is on a 200mbit line last time I checked, so could be under an hour.
If only we had network graph stats.
