open balena api doesn't seems to recover cert modification

I’ve followed the step in this thread (VPN Certs seems to be expired - #10 by wolf_karl) and manually create certificates for the vpn and root.

There’s nothing in that thread about updating DEVICE_CONFIG_OPENVPN_CA

Just to be sure, I should take the ca.crt in the /open-balena/config/certs/vpn directory and update the OPENBALENA_VPN_CA_CHAIN variable in the activate file?

Thanks again
