Error code: WaitforConnectFailed

[laser132217]

Hi,
Yesterday I set up Teamviewer on an Acer notebook (running Windows 10) in order to remotely access it from my Macbook Pro. Both are on my home network and the Acer is connected directly to the router via ethernet.

The Acer appears as online in Teamviewer on my Mac however when I go to connect to it, I'm given the following error code:

No connection to partner!
Partner did not connect to router.
Error code: WaitforConnectFailed

If I keep trying to connect, occasionally it will work but 9 times out of 10 it wont. However, for some reason resetting the router seems to do the trick. Obviously this isn't ideal.
Here's what else I've tried: Toggling router firewall (no effect), checked Windows 10 firewall isn't blocking Teamviewer, reinstall Teamviewer on Acer, restart both PCs.

Any advice?

Are you using use LAN exclusively in advanced settings?

Thanks for the reply. I've tried setting it onto accept LAN connections exclusively but when I do that the client goes offline and isn't accessible from the Mac (just to clarify, the Mac is connected via Wifi not ethernet - I don't know if that makes a difference).

Update -

I seem to have solved the problem. My Private Internet Access VPN was running on the PC being controlled and this for some reason seemed to be causing the error. Disconnecting the VPN allows me to connect to the PC perfectly now. Any ideas why this might be and whether there is a workaround that would allow me to keep it running while the computer downloads stuff whilst retaining access with Teamviewer?

If the VPN is running, then all network connections are via the VPN

Perhaps the supplier of your VPN blocks teamviewer
