OpenVPN TCP 443

I'm running an OpenVPN Server Version 2.4.4 on my Ubuntu 16.04.3.
The VPN connections work absolutely fine with UDP 1194 but when I try to change to TCP 443 it just won't connect.
Im using an apache2, which I turned off before testing with the command service apache2 stop.
ufw tcp 443 is allowed but even if I turn the firewall off, it wont connect.
(Also on the Windows client)

Here is my server config:

port 443
proto tcp
;proto udp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem

ip addr show tun0 with UDP 1149:

ip addr show tun0 with TCP 443:

Device "tun0" does not exist.

Anyone knows why it wont work when I change to TCP 443?
