Setup resin.io behind corporate proxy/firewall

I am having the same problem. I installed the development version of resin OS and I configured the proxy through redsocks as indicated.
After booting, I get the “Booted - Check your resin.io dashboard” message, but regardless of what I tried, my device doesn’t show in the dashboard.
From my local network i can access the device through the resin CLI:
sudo resin local ssh 00bc0c9.local --host
Then I can check if the redsocks configuration is correct and the status of the service:

root@00bc0c9:~# cat /mnt/boot/system-proxy/redsocks.conf 
base {
log_debug = off;
log_info = on;
log = "stderr";
daemon = off;
redirector = iptables;
}

redsocks {
type = socks5;
ip = 192.168.1.102;
port = 4192;
local_ip = 127.0.0.1;
local_port = 12345;
}

root@00bc0c9:~# systemctl status redsocks.service             
● redsocks.service - redsocks transparent proxy redirector

However, when trying to run
root@00bc0c9:~# curl https://api.resin.io
it doesn’t do anything.If I add the proxy as an env variable:

root@00bc0c9:~# export http_proxy=192.168.1.102:4192
root@00bc0c9:~# export https_proxy=192.168.1.102:4192
root@00bc0c9:~# curl https://api.resin.io
returns

<html lang="en">

which seems ok. Also, I can see also some activity on the proxy server:
sudo tail -f /var/log/squid/access.log
returns
1520348904.067 948 192.168.1.106 TCP_TUNNEL/200 5486 CONNECT api.resin.io:443 - HIER_DIRECT/52.86.191.185 -

Any ideas as of why the device doesn’t show on the dashboard?

Thanks!
