    What's happening is probably that you have Kapersky Anti Virus on your PC. For some reason it makes OCSP-over-HTTP requests to the Duet. This means that the requested filename is extremely long, like a virus attempting a buffer overflow attack.

    In firmware 3.1.1 the warning is suppressed if the filename looks like an OCSP request.
