Erorr when trying right user&pass pair against krb5-kdc

[prazape]

As I was getting to know how to use this i wanted to test it against just few users (knowing which are good and which wrong) and few passwords (with one right).

Discovering users work fine, but I always get "no password discovered" even though I know there is one correct pair.

After adding -debug, and get an error:

I am running it on clean, freshly installed deb10, with locally hosted krb5-kdc. Kerbrute was installed via pip3.

Got any idea what can be the problem and how to solve it?
