Quickbooks error 15215 server not responding occurs when there is another application running in the background when we try to download a payroll update in our system. The application, which may be a program, demands a lot of bandwidth, which prevents QB payroll from making a connection with the server. And this error restricts us from accessing the server that leads to no response. The Quickbooks user should keep in mind to update and also upgrade the software after the regular intervals.
