OpenVPN, Windows works, Android doesn't, help?

HI allBit of a technical one so hoping I can get some help here

I have a OpenVPN server running at home, and I have it working from my laptop, just not my phone.

I have my laptop (windows 10) and android (one plus) connected to the same WiFi (Friends network)

My laptop I can browse to both internal services (NAS and Dev web server) and external websites (Google showing public IP as my home's IP)

My phone I can get internal services, but not external ones

I can see the traffic from my phone on my firewall leaving to the internet, but I can't get detailed enough logging to see w hats coming back(I could try find a w ay to get logging if needed)

Im a little lost as the only difference between these is windows vs android, the routing and networks are exactly the same otherwise, so im not sure why its not working as i expect it toany help would be appreciated.

For reference:Server: Ubuntu 16.04VPN IP Range 10.10.101.xVPN VLAN 10.10.100.xStatic route pointing 10.10.101.x to server IP on 100 network
