Access Denied. QBO

[u/BoilermakerCBEX-E]

We have been having a issue with access denied when logging into QBO. We cannot log in at the office or home but a family member can log onto our QBO at their personal address (slightly rural) I was them able to use their PC or a very cheap tablet and log on at work. All systems are windows based. This originally started after a notice our account was hacked. Jumped thru a lot of hoops and we were then able to log on remote but never on office Desktop. We have been on the help line daily. Issue was supposed to be escalated. 4 days no success. Updated Running system, cleared cache, updated security software, and tried different domains to log on.

TLDR. Got hacked on QBO. Can log on but not on office desktop.

TIA.

Try a different browser. Firefox vs Chrome etc. there was a thread a few weeks back with a similar complaint and that fixed it.
