Here's the error message from log file:
2021-04-22 12:45:50,991 DEBUG [RxComputationThreadPool-2] history.HistoryExtensionKt$retry$2 (HistoryExtension.kt:26) - History call no 0 failed with com.dukascopy.api.JFException: Instrument [EUR/USD] is not subscribed

But EUR/USD is already subscibed in JForex.

So what's wrong?
