Different errors at different times: 103 / 107 / 185.  Looked up the codes via your string as since I've reconnected several times, ruled out 103 and 185.  However, 107 is a new one on me.

As for uploading .csv files, no need/avoiding this as I prefer the convenience and accuracy of downloading the transactions.  The connection works temporarily after reconnecting via the link provided in the error message and therefore, I can stay up to date.  However, ideally and as suggested, the connection should be maintained.

Thanks for any and all help...
