This error on my home wifi network started just recently. A few days ago, I was trying to purchase a subscription from apple but verification always fails, I tried switching to mobile data and it worked successfully. There are other apps and websites I could not access anymore. It seems to be a problem with the network (my home wi-fi) since everytime I try to switch my connection to mobile data, it always works. When accessing some websites, prompt messages show “The network you are connected to has been blocked due to suspicious activity,” while the other website show “Your computer/network is banned for possible bad behavior”. I hope somebody can help me, its been stressing me out for days 🙁 Thank you!
