OpenVPN reconnect issue on V1.4.1.30_1.2.26 Firmware

I just bought a R8000P NightHawk Wifi Router and I uploaded (not manually) to the last firmware V1.4.1.30_1.2.26.

 

My problem is that once a VPN connexion has been stablished with the R8000P, it is shown always connected on the attached devices tab. Even if the client is disconnected. Then, if I try to restablish the VPN connexion, it will always fail. The only solution to allow again a VPN connexion is to restart the VPN service.

 

Searching on the NETGEAR comunity posts, I've seen that the "VPN reconnect issue" was supposed to be solved on the Firmware Version 1.3.0.10. Is that a regression ?

 

Thanks in advance.
