I have this running now after a bit of futzing,, thought this might help others

Netgear R6800
Firmware VersionDD-WRT v3.0-r52869 std (06/02/23)
Kernel VersionLinux 4.14.315 #3922 SMP Fri Jun 2 13:35:48 +06 2023 mips

Running Openvpn Server

After I flashed from Netgear stock firmware to current firmware (which was /betas/2024/03-19-2024-r55416/ or /betas/2024/01-02-2024-r54682/) the HTTPD service kept crashing. It would stay up for about 2 mins, then crash again.
the fix was to ssh in as root and run erase nvram && reboot

Now that the gui is stable, I went to setup OVPN server as per my normal setup. The OVPN server would not stay up. I kept getting messages like

"dco_new_key: netlink reports error (-10): Operation not supported"
when the client would try to connect..
Also the ovpn server would crash.
this was on both of the current levels.

Flashed the router back to /2023/06-02-2023-r52869/
NO changes to my OVPN server or client config, and all is well.
This is the same ovpn client and server config that I run on other R7K's and one R8K

Thanks

Topic moved to hardware-specific forum (for now). I'm sure if you had read the documentation in the Advanced Networking forum, you would've figured out how to be on the current release without issues with OpenVPN.

Sticky: OpenVPN guides and documentation

I'm fairly certain that sir @egc will chime in at some point, and possibly move this to the Advanced Networking forum, or not.

From the documentation already mentioned and from the changelog:

53787
DCO (Data Channel Offload) added. As it is a WIP it can cause connection problems so in case of problems (no connection or connection but hang or no traffic) disable it, add in the OpenVPN Additional config: disable-dco
