Chromium VPN DNS failed

[kebra777]

Thanks for your work.
I try to use chromium with openvpn.
I have followed your tutorial.
When i launch Chromium-vpn all site can't be reached (err_name_not_resolved)

When i check oz shell, dig command solve myip.subgraph.com :

;; ANSWER SECTION: myip.subgraph.com. 600 IN A 185.26.124.87 ;; Query time: 668 msec ;; SERVER: 209.222.18.222#53(209.222.18.222)

I use your OZ profile (https://support.subgraph.com/openvpn-test/chromium-vpn.json)

In daemon.log i can read :
[chromium-vpn] Child process pid=673 exited from init with status -1

Chromium without vpn working well in OZ sandbox (but with my real ip address)

How to solve this
Thanks
