Hello Community Users, In the case the reconciliation balance is not correct but the bank chart of account is and there's nothing you can see that has not been reconciled in the chart of accounts when searching the filter for not reconciled and there is no deletions/edits of amounts from a previous reconcile. The best solution is to go to the reconciliation history and find the reconciliation where the balance was correct. Then ask the accountant user to undo the reconciles up to that date and go back through those ones. 

If this is the only reconcile you have done and the start balance is correct we'd suggest undoing it and then running the reconcile in shorter periods say for example monthly . Then it will be clear at what point it has deviated from the bank balance
