Q: Why is proxychecker.vultr.com trying to connect to my IP? As part of routine security scans, Vultr.com attempts to identify open proxies during the login process. Q: How can I stop this? We would suggest that you ensure you aren't running an open proxy (such as Squid). If you are running a proxy, please ensure that it is only configured to accept requests from your IP space. If you're just seeing hits in your firewall, these can be safely ignored. Q: Can you stop this check from running? These checks are only run when you try to log into the Vultr control panel. If you aren't attempting to log into the Vultr control panel, and you're still seeing probes, this is a good sign that your machine has been comprimised. Q: What if I have more questions?
