AC68U - OpenVPN regularly dropping

[Evansgo]

I have an AC68 with firmware 378.53 and have never tried this before so this could easily be a simple mistake. I set up the VPN specifically to give me a UK IP and specifically OPENVPN as I needed the individual IP routing capability (fantastic!) not for security.

It all works fine for a while, but if the VPN is not used it drops out frequently, I have amended the Poll Interval to keep it alive, but really wanted to see if I could fix it properly.

Here is a snippet of the log, hopefully where the issue is....

Would someone please take a look for me and see if it is anything obvious?

Corrupt config?

Also, when you get a chance, check your local DNS servers - looks like you're using Google PublicDNS - and those are at 8.8.8.8 and 8.8.4.4 for IPv4...

Similar thread over here...

Thanks for that, I spotted the DNS just after I posted it and have now changed it. I did wonder about the config, but it works every time I manually connect so thought it wouldn't be that. Also I did find that thread thanks, but it didn't help me, probably due to a lack of knowledge....
I tried messing about with the custom commands but as I'm doing it by googling each line, its a bit haphazard

In case it makes a difference I'm using pureVPN and set it up with their web site help. The custom list is:-

mute 20
float
route-method exe
route-delay 2
auth-retry interact
explicit-exit-notify 2
ifconfig-nowarn
auth-nocache
