Thanks for your reply.
I've made a mistake with the pbbanshub.
I've just done what you say
In my pbsv.cfg, i have that now:
;PB UCON Settings / Lists
pb_sv_usessionlimit 3
pb_sv_ucontimeout 300
pb_sv_uconempty
pb_sv_uconadd 1 "64.27.21.46" "pbbanshub" "pbbanshub"
pb_sv_uconignoreempty
I think the server is properly configured now
