Guys, I’m having a connection error problem on Roblox and I can’t fix it at all. It’s on my daughter’s PC. I’ve already restarted the modem and nothing. Will I have to format it?
Sorry. There was a problem accessing our servers.
The error that’s appearing on my screen is this one:

Our internet plan is from Oi and other games and websites work normally.
Is Roblox down or was I banned?
Help, please!
