Tone and manner, as well as context, would tell if this is empathetic or slightly rude. If someone tells you they tried something but failed, you can comfort them by saying "(au moins) vous avez essayé". As a question to someone complaining or blaming others, you may ask "(au moins) avez-vous essayé ?" and this would be (not rude) but authoritative or educational.
As is, the sentence here is quite neutral, since we don't know anything about the circumstances.
