Klar not able to connect to clair server

[jeannotjunior]

Hello all,

I have some issues using Klar to analyse some images with clair.

My setup :
I have deployed a clair and database instance on an Openshift cluster.
I use clair:v2.1.7
with 6060 and 6061 as target port
and Postgres:9.6 with port 5432

My config.yaml

clair:

I did configure a route to be able to communicate with the clair pod using Klar on my local machine.
here is the output of the corresponding curl

curl -X GET -I http://myclairroute/health
HTTP/1.1 200 OK

here the output of Klar

I can ping http://myclairroute from my local machine without any problem , although it is worth mentioning that I need to be. connected to a vpn to do so.
