Does it also happen to you that every time you restart the decoder the "openvpn" directory with the upd files inside disappears? How can it be solved? I created the "openvpn" folder on media/hdd.
Are you certain folder has disappeared, I do not use vpnmanager now but I still have various different vpn suppliers folders still on my hard drive
but have them named as supplier example SurfSharkVPN, FastestVPN, NordVPN , IvacyVPN and some I do put UDP and TCp into different subfolders check you paths in vpnmanager make sure you have it set to just folder with UDP files and not all files in one folder.
