This literally happens to just about everyone whether they play on mobile/PC/Graal PC servers. It's not an issue on your end and pretty sure there's nothing you can do about it. It's an issue with Graal's client itself and it's servers. So this'll keep happening to you, until Graal's management decides to look into it and get it fixed, which is obviously farfetched and doubtful that it'll happen anytime soon. But good luck on finding a solution!
