I have exactly the same problem as this. I also find if I'm having a really hot session once I've been playing for a round 4-5 hours all games have internal server errors or token errors it's so frustrating when players you watch stream play sometimes for 10-12 hours with hardly any off these problems. Example I played at a casino and hit 2500x on a quid then lowered the stake to 60p for the rest of my session but after 3 hours off a massive bonus hunt no games would load at all and it kept logging me out the casino. It all felt dodgy and rigged. The casino is in charge at the end of the day and I do think responsible gambling comes into play and they can restrict your account for a short time without you necessarily knowing i.e internal errors etc. Will we ever know??
