Experience with soju bouncer

I have been trying to connect to HackInt(tor) through soju and am hitting a wall where I use certfp to add hackint cert and then I try to use sasl set-plain … to enter my sasl creds but when it tries to connect I keep getting stopped with some bs about EXTERNAL auth from certfp does anyone know how to get around this? Or maybe have a server recommendation for another server that allows for anonymity.
