When the program is unable to access the company file, Error Code 6177 in QuickBooks appears. This usually occurs when an unsuccessful connection occurs when QuickBooks attempts to open a file that is stored on a server or remotely. Network problems, corrupt company files, and improper folder permissions are common causes. Make sure the file path is accurate, check that the hosting settings are set up correctly, and make sure the network connection is stable in order to fix this. You can potentially avoid this mistake by upgrading QuickBooks on a regular basis. Should you wish to talk with a qualified QB, please call 1.855.856.0042.
