i have this same issue since yesterday. Opened a ticket and the CC replied me a general copy and pasted response. " reboot the phone, exit all the apps, make some space, reboot the router... such bs. This is obviously their server problem.
I have the same problem yesterday (11/17/2020) How it could be solved? All of my Guild can not logging into our account because the error code 1-54. Help us, please. Thank you. Note: The name of Our Guild is Siegefell. We have total 5 members.Fivehard is Master and Nam365374 is General.
