Why can't I access my bank account on my MacBook Pro?

i now have 3 browsers google chrome, edge and safari on my MacBook Pro and cannot get into my bank account with any of them i just watch a circle going round until i get bored and come out of the browser

from that i have to assume it is not any of the browsers. this seems to have happened after a Mac update

anyone got any ideas as to what is wrong
