Maybe it's because speed of internet connection, especially if use a VPN because sometimes using a VPN makes the internet connection slower a bit, especially if it's freevpn, because sometimes I also experience the same thing when the internet connection is not good and indeed loading page is quite annoying because it will reappear if we refresh the browser.
The connection via FreeVPN is significantly slower than without VPN, but that mainly affects streaming services. However, this should have absolutely no effect on normal browsing or games like on Rollbit, since the required bandwidth is very low here. I guess it was a general internet problem either on Rollbit's side or on the user's side. What also often helps is to clear the cookies in the browser or to open the page via a private tab!
