Teamviewer Wake On Lan Not Working

Hi all,
I use TeamViewer, have for years - great too - especially if I am travelling and want to securely access something on my home PC, I can access it from TV mobile or from my laptop. I use to leave my PC on, mainly for this reason.
I was reading about how to enable TeamViewer to use wake on LAN - meaning if I could just have my PC sleeping, and then send a wakeonLAN message to wake it up when I need to - access what I need -then have it sleep again. Saving power etc. I have read on the TV site that I can do this from either mobile or laptop via internet.
I have read the TeamViewer instructions on this, and while it seems a bit complicated I thought I have followed it - but I cannot get it to work. Hoping some of the experts here can guide me and help troubleshoot for me?
Firstly, I am running Win 10, latest version of TV - plus 'Teamviewer for Remote Control' on Android.
My router is running Gargoyle, and my ISP used dynamic IP's.
Here are the guides I have been following:
1) https://www.teamviewer.com/en/res/pd..-on-LAN-en.pdf (Yep I know it's for TV 9, but I can't find an updated version)
2) https://www.teamviewer.com/en/help/4..eamviewer-work (their support page)
As I want to do this from the internet, it seems I need a dynamic DNS provider. SO, here is what I have done so far:
- Set up a free dynamic DNS domain via changeip.com (it's set up using the domain (myname.changeip.org )
- PC is set to enable wake on LAN in BIOS
- Network controller has both 'allow this device to wake the computer' and 'only allow a magic packet to wake the computer' selected in device's power management settings, and also the option 'wake on magic packet' is enabled (from advanced tab)
- Team viewer is configured with Wake on Lan enabled for public address - I used the domain above (myname.changeip.org), and port 9
- In my router, in the Dynamic DNS setting, I added the same domain (myname.changeip.org)
- In my router, I added a port forward - type UDP, from port 9, to IP 192.168.1.254 port 9 (wouldn't allow 255) this part was a bit confusing in the TV instructions but I think this is how it should be
When I turn the PC to sleep, and then try and access it via teamviewer on Android, the PC shows offline. There is an icon that looks like a power icon, but clicking it does nothing. And yes I did test it using the mobile phones network, not from my home wifi.
WHat am I doing wrong?

Hi guys
I hope someone here can help me as I cannot find any recent topic which covers this.
My problem is that since recently my PC wont boot from WOL when completely shutdown. If it's in standby then it will turn on from WOL packet but not when it is shutdown.
For this reason I believe my issue is NOT Windows related, as Windows the issue exists only when the PC is completely turned off.
It used to work fine, with Windows 10. I've not reinstalled the OS but I have installed all updates when released.
I read about the Fast Boot causing the problem for Windows 10. But even after disabling this and rebooting a few times it still doesn't boot from WOL..

When turned off I can see on my switch that the link is also down. Whereas when on standby I see the link is set to 10mbps so I know the NIC is off when the PC is shutdown.
This leads me to think it's a bios issue.
I found the EuP and PCIE Wake options. I experimented with different settings. Originally it was with EUP on (S4+S5 enabled) which from what I understand gives Windows the control to decide how to shut it down. I tried disabling that and setting PCIe wake enabled, but this hasn't resolved the issue.
I know it CAN work as I used it a lot last year when on holiday, always from shutdown. I know the WOL packet is good because it boots out of standby.
Please help! Why can't I get it to work from shutdown?
Thanks
Matt
