The two most recent networks I see connecting to the account are both cellular networks, which do often get detected as proxies/VPN's due to prior abuse and because of their "decentralized" nature. The signup network was different however, and we would recommend using the original signup network as that one is known to not be a vpn/proxy.
The other address was at a public place, as I could not sign up at my home WiFi, and couldnt sign in either, so I tried using Cellular Data, and I want to signin to my account on my home WiFi.
