+ AA6YQ comments below
At the completion of a WSJT-x QSO, instead of logging the QSO to DXKeeper this error message pops up. It is possible to manually log contacts.
+ Attachments are not conveyed here. What is the text of the error message?
+ Are you using the direct interoperation between WSJT-X and DXLab, or are you using JT-Alert?
+ Have these error messages always appeared, or is this a recent phenomenon? If the latter, what changes to your software or hardware did you make around the time they first began appearing?
