I have a brand new RUT240 and installed the zerotier package, ok.
After I enabled the zerotier vpn, the router seems to lockup after a couple of minutes. It will only work again after a power cycle at which point it will stop responding after a few minutes.
If I disable the zerotier VPN, the router seems to fine again.
I have tried Two brand new out of the box RUT240 routers, one with the installed firmware 1.31. and one with the latest v14 installed and both routers do the same thing. I have even tried two different SIMs from different providers.
I can only assume I am configuring something incorrectly but can't imagine what this is, they are barely configured, just out of the box.
Thank you for any advice.
