Errors when testing with httprint

[mzfr]

I was testing httprint on Snare for issue mushorg/snare#7.

$ sudo python3 snare.py --port 8080 --page-dir example.com

This occurred when I ran this command on httprint: httprint -h 127.0.0.1:8080 -s signatures.txt -P0

aiohttp.http_exceptions.BadStatusLine: invalid HTTP method

@afeena was able to figure out that tanner cannot handle this request so it returns nothing for dorks

[afeena]

aiohttp.http_exceptions.BadStatusLine: invalid HTTP method occurs than httprint sends this raw data:
b'\x16\x03\x00\x00_\x01\x00\x00[\x03\x00[^*\xdd\x9a4\xfc,\xf1#\xd9\xa5o\xed\xa5v~\x13I\xf0\xef\xc0js[\x9dm\xa2\xf2@\xadx\x00\x004\x009\x008\x005\x00\x16\x00\x13\x00\n\x003\x002\x00/\x00f\x00\x05\x00\x04\x00c\x00b\x00a\x00\x15\x00\x12\x00\t\x00e\x00d\x00`\x00\x14\x00\x11\x00\x08\x00\x06\x00\x03\x01\x00'

Exception occurs inside aiohttp and doesn't affect the result of httprint or snare work.
Other exceptions no more relevant after replacing redis library.
