2023-04-23T04:09:36Z 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”
2023-04-23T04:09:36Z WRN ICMP proxy feature is disabled error=“cannot create ICMPv4 proxy: Group ID 0 is not between ping group 1 to 0 nor ICMPv6 proxy: socket: protocol not supported”
