Failed to get update please check internet connection


I have a newer iPhone 10 and updated hearthstone a day or two ago and was working fine until about 2:00 est and has given this error every time I login. I have reset my phone, changed internet, used normal 4G LTE and even deleted the app and reinstalled. Looking for a fix on the issue as I just bought the single player advantage (full run) and can’t do anything now


Went to open hearthstone on my iPhone 8, it started to update. Then my phone turns off because of battery save mode, and I reopen hearthstone and got this message. It won’t attempt to re-update itself and there is no update available in App Store. Forever quitting hearthstone, I guess.
