I cant connect any testing installation to my OpenVPN server running MikroTik Gateway at my customers premises. It is running for more than a year and all ovpn clients from XP (sadly) to 10 can successfully connect. Rest of the firm is powered by Debian Jessie and even those client can connect without any problems.
But Stretch cant connect at all. I have got network-manager-openvpn-gnome and network-manager-openvpn with with all dependencies installed, configuration is correct (i have even setup new stable and testing clients side by side), but stretch just cant connect.
Im using CA certificate with user credentials and AES-256-CBC, all configured through Network Manager OVPN Gui Wizard.
Mikrotik shows "disconnected <internal error>" and "<TLS error>" at its log (picture), i will have to dig little deeper for further information from MikroTik, if i have to.
