I thivk, it is the same issue https://github.com/cuckoosandbox/cuckoo/issues/765 I have also been updated with the last version.

As part of #753 I added a tweak that at least gets rid of the exception that you posted (see also 22c3a2e39ac3c6770d735e6ef1bf96e206fea302). Please upgrade to the latest version and also share a pcap file as outlined in #765. I'm still not sure why you're getting this error ;-) Thanks!

Can you paste the entire http request/response, i.e., curl -vvv 192.168.56.101:8000?
