WRN The user running cloudflared process has a GID (group ID) that is not within ping_group_range. You might need to add that user to a group within that range, or instead update the range to encompass a group the user is already in by modifying /proc/sys/net/ipv4/ping_group_range. Otherwise cloudflared will not be able to ping this network error="Group ID 0 is not between ping group 1 to 0"

try to use command : sysctl -w net.ipv4.ping_group_range="1 2147483647" sysctl: permission denied on key "net.ipv4.ping_group_range"
