Problems with Cortex Mobile

hey since the end of this summer i have been getting the message "oops cannot connect to server" i have been able to get to the login and when i try to log in i get the message "JWT token expiry value us more than 50h" Is there any fixes to this as i planned to buy myself a birthday present with my silver but my earnings were seriously reduced because i could only use the pc version and i am very disappointed. (my parents are getting me the raiju ultimate and i feel bad because it was very expensive, even with the 25% off voucher) I have tried uninstalling and installing it again, it didnt work. Any help is appreciated thanks in advance Screenshots==
