It would, but through nobodies fault but your own. And you can easily fix it by allowing the outbound ports. While there are some uses for blocking outbound traffic, they are usually rare and most useful when trying to control what software can talk to the outside. Because of that I would recommend whitelisting outbound traffic on all ports on a per process basis, though I’m not sure how to do that if the firewall is not on the same machine. You could of course allow outbound traffic for this machine on the router and run a local firewall to block outbound traffic except for the processes like uplink who require it.
But if you’re blocking all outbound traffic on any port you’re going to run into these problems a lot. Most software expects outbound traffic to be fine as it poses much less of a risk.
