It looks like a mismatch between pynetbox v3.4.6 and NetBox v2.5.8 --I built this script using NetBox v2.4.4 and current version of pynetbox is 4.0.6.
I can't reproduce this environment right now (NetBox v2.5.8), but just made a new commit updating all versions of dependencies. Please, try this new version and send me a reply (it worked for me pynetbox v4.0.6 and NetBox v2.4.4).

pynetbox.core.query.RequestError: The request failed with code 400 Bad Request but more specific details were not returned in json. Check the NetBox Logs or investigate this exception's error attribute.
Connection reset errors could be related to network or web server issues. Using the same environment you're running the script, you could open Python shell and simulate that interaction:
>>> from pynetbox import api
>>> nb = api('netbox_addr', token='token_goes_here', ssl_verify=False)
>>> nb.ipam.ip_addresses.get(address='ip_addr')Try with IP addresses that are registered and not registered in NetBox. You could even try with some invalid values, like address=None or address=84. How will NetBox behave?

Thanks, this actually was helpful debugging.
The issue seems to have been caused by using the short name for the netbox server in the scanner config instead of the fqdn that Netbox has in the ALLOW_HOSTS setting.
With this and pynetbox==4.0.6 now the scanner is aadding new IPs to netbox!!!
