Socket networking problem with updated version of cvefor method

[mic-caggiano]

The fix Alexandre provided for the previous issue with the same method worked just for a while. Now my output is a new error which you can find below. I'm using the Python wrapper of cve-search (PyCVESearch) for remote requests on cve.circl.lu, shall I update any module in Python3 or through pip?

EDIT: now Python APIs (specially cvefor method) work, but response to cvefor requests is very very very slow (cve.cvefor('cpe:2.3:o:canonical:ubuntu_linux:16.04:*') lasts something like 25/30 minutes to output a JSON object). Quite difficult to handle and I'm using them into my master thesis.
