I run the IPFS daemon on Hetzner, and it was trying to connect to local IPs because of some misconfiguration. They sent me an email saying my server was portscanning their LAN, and I should fix it and email them how I fixed it.

I didn't know what they were talking about so I replied saying that, they helped me shut down the local port connections and I never heard another complaint from them. There was no downtime or banning at any point.
