Issues with server Internet dying randomly (dietpi)

[froodle]

Having an issue were my dietPi's internet is dying randomly after 1+ hours of being online, seems to be randomly timed

Raspberry Pi running DietPi connected by wifi
Running OpenVPN on startup
cant see any logging related to it even after chaning dietPi's logging to store it all.
It seems i can still get local access to it on the network but no internet on it
I wonder if its issue with the OpenVPN


ip link show shows
