iCloud drive has stopped responding

I get the following error message when trying to open iCloud Drive from my MacBook Pro using Safari or Google Chrome. Tried logging in from a windows pc and got the same error message. I am able to open the iCloud Drive location from the finder but not through a browser. Please help if possible, this has been going on for some time now and is getting really annoying since I am unable to find any answers when searching for this issue on this site or on Google.
