Yes, I have cleared my cache, cookies, all my internet data. Restarted multiple times. This is only a problem on this PC. Everything else is fine. I can connect to those websites on my dad’s computer and on my iPhone. (All on the same network).
You can figure that out by changing your DNS settings to point to google’s DNS. I sometimes get issues with pages not loading and this usually helps me.
I don’t get an error message. Nothing happens. Task manager shows that RobloxPlayerBeta.exe doesn’t start at all. But if I enter incorrect arguments then I get an error message appropriate to what I entered incorrectly.
Also, roblox isn’t the only website. www.speedtest.net yields the same problem (the page just loads and loads and nothing ever shows up).
I can log in on my virtual machine (which is strange) and I can log in on my phone and on my dad’s PC.
api.roblox.com isn’t included when you’re IP banned, meaning you would still be able to access that page, so I don’t think that’s the reason at least. Though, that being said, I have no idea what the cause of this is then.
There are also systems put in place which automatically IP ban people, meaning your account wouldn’t be touched. For example, ddos prevention. However, it still doesn’t sound like you were actually IP banned.
