zoho mail not opening in safari

zoho mail not opening in safari

my zoho mail was working fine until around 11am this morning (uk time), it then put me into the login screen, now everytime i try to login i get the please reload page and try again message, this is only happening in safari i can login with firefox to access mail, but i would prefer to use safari. i have allowed cookies in my safari settings. is there a fix for this issue?
