@RymkusDev could you please fill in the template provided, I can’t help without proper debug information so I can reproduce the issue

[Luke Paris]

Fixed issue template for you, it also appears you're using the gzipped version of the wordlist, and not the actual text file. You'll have to unzip it as such before use:

$ gzip -d /usr/share/wordlists/rockyou.txt.gz
