Unable to verify server certificate or connection not fully completed

[Kenneth Gil]

I wanted to play multiplayer with a friend and I can not do it, when I enter multiplayer and multiplayer room asks me to create an account, when I register and I get a message "could not verify the server certificate or the connection was not completed at all", also if I go to multiplayer and join the game, when I click continue a message appears "It has not been possible to connect to the server, usually happens when the UDP port 20595 is not redirected to the host, or by action of a firewall or antivirus". I disabled the firewall but it still gave the same error. My friend is from Spain and I am from Ecuador, I don't know if it has something to do with this. I hope you can help me, thanks. (Note: I speak spanish, this message was translated on the internet)
