remote scan failed (from centos to centos)

During a remote scan with scap-worbench, from one CENTOS to another CENTOS, I got an error (see the log below).

What is amazing is that we do not have the askpass popup to authenticate (stdout redirection problem?) Whereas if I launch a DRY SCAN (with the same machines) in a terminal, everything is OK

Is there an ASKPASS or other variable concern? thank you.

OTher things : scap-workbench is not launch with root

DRY RUN: is OK

oscap-ssh user@computer.francecentral.cloudapp.azure.com 22 xccdf eval --datastream-id scap_org.open-scap_datastream_from_xccdf_ssg-rhel7-xccdf-1.2.xml --xccdf-id scap_org.open-scap_cref_ssg-rhel7-xccdf-1.2.xml --profile xccdf_org.ssgproject.content_profile_pci-dss --oval-results --results /tmp/xccdf-results.xml --results-arf /tmp/arf.xml --report /tmp/report.html /usr/share/xml/scap/ssg/content/ssg-centos7-ds.xml

Another thing: the scap-worbench command line launched in a terminal seems good (an askpass window appears to authenticate): /usr/bin/setsid /usr/bin/ssh -M -f -N -o ServerAliveInterval=60 -o ControlPath=/tmp/ljXSlY/ssh_socket -p 22 user@computer.francecentral.cloudapp.azure.com
