Hello @topomax. Does it happen as soon as you click on Login link?

When the error message appears please click Details tab and post whole error message content here.

… or

Find log.txt file under [MyDocuments]\SambaPOS4 folder, convert to a zip file and upload it here. You can upload by dragging it inside post editor or clicking up arrow button.

Thank you very much in advance for helping us to identify the issue.
