if you look at the picture shared by that person, it looks like he's having problems on a slow network. so that when you are accessing Duelbits you cannot enter or get stuck on the first Duelbits screen.
i say this because i have experienced this before and i thought something was wrong with the Duelbite site, but i thought wrong. when I don't access Duelbits I try to open another site and the result is the same can't access other sites. it's definitely caused by the network.
but there is also another problem, the possibility that the desktop storage is full, which causes the performance of the computer to decrease when accessing the Duelbits site.
This problem is only happening in my house, no matter which device or browser I use. I have not been able to solve it yet.
But I was able to place the bets from my cell phone connected to the 5g network.
I have tried almost everything here, I don't use VPN, later today I will call my carrier and ask them to reset my connection.
I'll update later with information.
I'm having the same issue for couple of days already. Tried in two browsers with the same result.
As I said above, I'll try to call my carrier, I'll update later with more info.
