The error 102 occurs when QuickBooks Online (QBO) is unable to connect to your bank's website. The most possible reason for this is your bank is undergoing maintenance, or there is a server issue. We can check your bank's website first to verify this one.
In most cases, this error message usually fixes themselves within 24 hours.
To resolve this one, just manually update your bank account. Let me show you how:
