error: remote control failed ssl crypto error:0A00010B:SSL routines::wrong version number

[jonnotk]

there seems to be an issue in scraping unbound Version 1.19.3 and the latest unbound_extractor version.

the unbound.log shows :

unbound[875:0] debug: new control connection from local
unbound[875:0] debug: comm point stop listening 20
unbound[875:0] debug: comm point start listening 20 (120000 msec)
unbound[875:0] notice: failed connection from local
unbound[875:0] error: remote control failed ssl crypto error:0A00010B:SSL routines::wrong version number
unbound[875:0] debug: comm_point_close of 20: event_del
unbound[875:0] debug: close fd 20

and service status reports :

my unbound_exporter command line is :

unbound_exporter -unbound.ca "" -unbound.cert "unbound_control.pem" -unbound.key "unbound_control.pem" -unbound.host unix:////unbound.ctl WorkingDirectory=/opt/unbound_exporter

all the files have the correct access rights and are accessible.
