Does your router have an option called "Firewall" or "SPI-Firewall" by any chance?

That might block the traffic since most routers comes with it's own firewall system.

 

The other way around would be to use a VPN in the hope that'll solve the issue.

You should be able to find a few free VPNs through google.

Disbaled the firewall and now it works! Thank you very much!

Does it show any errors while starting the match?

Such as Connection Error 1-2 Connection In Progress/Connection Failed.

Unfortunatly, it doesn't, just the connection keeps failing, but there're no messages about it. I can join matches, but not start them, because of the connection problems.
