possible bug

[Darkcast]

first thanks for the script.

I am running this on python 3.9 on Catalina and I get the following error
ps the PII has been redacted.

SAP_RECON-master python3 RECON.py -H [redactedIP] -c -p [redactedIP]:[Port]

During handling of the above exception, another exception occurred:
