Config used

Current Behavior

container is restarting as it cannot ping the nordvpn server

ERROR: ERROR: OVPN: cannot ping https://downloads.nordcdn.com/configs/files, network or internet unavailable. Cannot download NORDVPN configuration files

Expected Behavior

nordvpn service is reachable, it seems we are checking in way that is currently no longer supported by the cdn

How have you tried to solve the problem?

pinging the server manually gives the same issue. It can't be pinged, but downloads work nevertheless fine
disabling the checkDNS part of the script makes it work again

here example of the manual testing (ping failing, but downloading works normally):

~$ ping downloads.nordcdn.com
