New info, with tcp works, with udp does not.

but at first, worked very well with udp.

if i do a port scan on TCP, openvpn port shows.

if i do the same thing when UDP is selected on ax20, openvpn port is not showing.

turned off firewall

Seems to be something with the router?

Hi, my public ip address as i do not have a static ip address service. When that happend, i re-exported de config file from the router with the new address, did not work. Then, i aquired a ddns service, which works when pinging, routes to my current ip address. Changed the ip in config file with the ddns, as in one of the faq step, did not work.

After that, i updated the router, still nothing changed.

Out of curiosity, I changed from UDP to TCP and was alive again, the openvpn client on my laptop, as well as on my phone, connected.

The only problem here is that speed has reduced. 

What seems to have stopped UDP from working? 

(First time when i configured the openvpn, when i got the router, worked on UDP out of the box, 'plug and play')
