ROS 7.0 beta3 - tool/fetch

Hi to all
i have this lines in “old” v6 setup’s, and working very well

:log info "Dynv6: update $host"
:local str "api/update\?hostname=$host&ipv6=$Wan6IP&ipv4=$WanIP&token=$ddnspass"
 /tool fetch address="dynv6.com" host="dynv6.com" src-path="$str" mode=https dst-path=("/dynv6.".$host)
:log info "Dynv6: $WanIP , $Wan6IP \n DONE";

but in ROS 7 it give following error:

status: connecting
status: failed
failure: ssl connection error: ssl: fatal alert handshake (6)

any workaround for this issue?
tnx

still same error in ROS 7 beta 4

status: failed
failure: ssl connection error: ssl: fatal alert handshake (6)
