Users encounter QuickBooks Error 6000 when they try to read, restore, or backup a company file. This is frequently the result of problems with the file, the network, or permissions. Access is disrupted by this problem, which is usually accompanied by a sub-code (e.g., -77, -80). To fix it, try checking the hosting settings or fixing the file.
