I realized what made the freebitcoin website unable to be accessed easily in recent days because it turned out that this casino was included in a website that was blocked by my ISP so I had to access it via VPN to be able to access it perfectly.
All sites containing gambling would be blocked by almost all ISPs in my country. Usually when a site is blocked a positive internet notification will appear but using Brave Browser the notification doesn't appear so I don't know that it has been blocked.
After being a member of this casino for quite a long time, freebitcoin was one of the casinos that could be accessed without a VPN, but now that's not the case anymore, and because FBIN is very VPN friendly, there are no worries about using a VPN.
It might be possible to get around a website block by changing the default DNS servers from the ones assigned by your ISP to something like Cloudflare's
1.1.1.1 or Google's
8.8.8.8.
The site have been pretty good for me as well, I mean; I can access the site perfectly and it loads just as fast as every other site I am visiting or accessing, but the only problem I am always and contacting having in the last few days is the free roll, each time I open the site and click on the free roll to claim some btc sats, I get this error message telling me that someone else have already played the free roll from my IP address; and I am to wait another one hour or sometimes, over 30 minutes to try again .
Many users experience this problem due to having a shared IP address. Maybe try connecting through your cellular network instead of your home internet or vice versa. If the problem is with your home internet then you can try asking if they can give you a unique static IP.
