I deployed dart shelf_router server to use as a service for my app.
Everything works fine in terms of service and code.
However, I see occasional (couple times per hour) strange request errors in journalctl logs, that I didn't make.
Why do these appear on their own?
I checked nginx logs and nothing seem to be coming from the outside.
As you can see below dart shelf_router also tell about different path, like "443", "80".

I'd be very grateful for any guesses and clues as I'm new to dart shelf!
