.wp6 Error line 281 Invalid Arg

[T3hpwn]

Hi,

I am a new user to the Tetra. I was able to set it up one time and never again. I did some searching for WP6 issues and none seemed to match my specific error/problem, so I am hoping someone here can help. I downloaded the WP6 and ran the Guided setup connected the tetra and saved the settings. I then selected Connect using saved settings and get  several errors: 

./wp6.sh: line 281: echo: write error: Invalid argument
iptables/1.8.2 Failed to initialize nft: Protocol not supported
iptables/1.8.2 Failed to initialize nft: Protocol not supported
iptables/1.8.2 Failed to initialize nft: Protocol not supported
iptables/1.8.2 Failed to initialize nft: Protocol not supported
iptables/1.8.2 Failed to initialize nft: Protocol not supported
SIOCDELRT: Invalid argument

I have checked line 281 and I don't see the error "echo '1' > /proc/sys/net/ipv4/ip_forward # Enable IP Forwarding" I tried changing the script on that line to 'echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward'  and I got the same issue. So, I commented out line 281 and manually enabled ipforwarding in  /etc/sysctl.conf but still no luck. I am running in root, I have deleted the wp6.sh script and downloaded a fresh one with the same issue. I'm on Tetra firmware v6.5
