Unable to connect to Quicken Cloud

I have an older version of Quicken 7.10. iMac too old to upgrade OS. Is EBILL not supported anymore on this version of Quicken? My EBILLS are no longer linked & when I try to link them I get a message that I can't connect to Quick cloud. I have tried turning off my firewall with no changes.
