QuickBooks error 6144 and 301 typically indicate a problem with accessing the company file or network issues. Start by ensuring QB is updated and your system meets requirements. Try renaming .ND and .TLG files, run QB File Doctor, or check for firewall settings blocking QB. If the problem persists, consider restoring a backup or seeking professional assistance.
