Can Firewalls cause Swarm not to build lighting?

Currently teaching UE4 at college and we’ve ran into an issue where swarm is blocked by the firewall and then doesn’t build any lighting at all. Is this a known issue with swarm and firewalls?

Hi Leon,

Swarm Agent can be blocked by Anti-virus and Firewalls. you’ll need to make sure that you’ve got exceptions in place to account for this.

Hi Tim,

can you point me a source where I can see which ports and programms need to have the firewall exception? I am struggeling with firewall settings caused by a kaspersky update.

Setting ue4editor and swarm exceptions was not sufficient. Port8008 and 8009 are still not enough, I guess. But kaspesky is not a real help to sort this out.

Greetings,
Lars
