I have two Hyper-V servers having the same exact issue, two different locations. Both running Debian 9 with OpenVPN. I used this “https://github.com/Nyr/openvpn-install” GitHub to setup. Everything has been running great, suddenly my clients are dropping packets and having disconnects. I have made sure Debian OS is up to date and rebooted both servers, but the problem continues. The only thing that will fix them temporarily is restarting OpenVPN with this command “/etc/init.d/OpenVPN restart”.
Any suggestions would be great.
