[unbound 1.10.0 | RPZ] throwing unbound-control error

[ѽ҉ᶬḳ℠]

Just adding (to otherwise working instance, incl. auth-zone and 
forward-zone):

rpz:
    name: test
     url: https://urlhaus.abuse.ch/downloads/rpz/


throws:

unbound-control[30270:0] error: connect: Connection refused for ::1 port 
8953
unbound-control[30271:0] error: connect: Connection refused for ::1 port 
8953
unbound-control[30272:0] error: connect: Connection refused for ::1 port 
8953
unbound-control[30273:0] error: connect: Connection refused for ::1 port 
8953
unbound-control[30274:0] error: connect: Connection refused for ::1 port 
8953
unbound-control[30275:0] error: connect: Connection refused for ::1 port 
8953

It is not clear to me how the RPZ config lines relate to unbound-control 
and why such error exhibits, thus help is appreciated to get this sorted.
