System says cannot stat (sysctl) but the values were set


I have set some netfilter (nf_conntrack) values in



After I logged in the netfilter rules were set to their values but

system on boot says cannot stat (sysctl) but the values were set after I logged into my system.

sysctl: cannot stat...

see picture:

Does anyone have an idea what the problem is?

Is the module conntrack loaded? lsmod | grep conntrack

xt_conntrack 16384 0
nf_conntrack 147456 3 xt_conntrack,nf_nat,xt_MASQUERADE
nf_defrag_ipv6 24576 1 nf_conntrack
nf_defrag_ipv4 16384 1 nf_conntrack
libcrc32c 16384 2 nf_conntrack,nf_nat
x_tables 49152 9 ebtables,xt_conntrack,iptable_filter,xt_tcpudp,ipt_REJECT,iptable_raw,ip_tables,xt_MASQUERADE,iptable_mangle

Workaround for me: (added all commands to file "/etc/rc.local"

sudo sh -c "/bin/echo 0 > /proc/sys/net/netfilter/nf_conntrack_acct"

and so on.
