Connection errors

[Deadshot-MISP]

Hello,

I am trying to connect MISP to our deep discovery director, I am at the first part of your guide, I edited the key.py file and ran python3 last.py -l 1h, and I get the below errors.

from your error , it seem tm-misp cannot connect to target , please check, for example you need connect to ddd
you need to allow connection port 443 from your misp host to ddd

I am not at that part, the connection I have only edited the keys.py file with the misp url and misp key, and then ran the last.py test. It is failing to connect to itself(the misp URL)
