Using an RB433 on 5.6 and after a reboot on the router Quickbooks Online won’t come up. Disabled all the drop statements and no change. Just for laughs, the station was isolated to an RB532 on 3.30 with no rules at all and same thing. All other websites seem to come up fine and QBO comes up fine on a workstation if we bypass the firewall. Could our mangle rules cause some kind of problem like this?
If you bypassed firewall and it worked then answer is obviously YES…
to help its neccesery to have more information.
like /ip firewall export
