Swarm agent crashing

There is a very similar question already posted, but in an effort to get some kind of response I’m risking the faux pas of posting this.

On build (lighting or otherwise) swarm agent boots up, then crashes.Unreal says “failed to connect to swarm”.

I have no firewall running and not anti-virus running. It seems to be a problem with verifying the ‘certificate’. I’m guessing this is some kind of .net issue. I have installed the latest MS updates of .net - so nothing funky going on there.

I have UDK from 2011 on this machine and that version of swarm runs just fine- unfortunately that doesn’t help me at all with unreal4 building.

Below are my logs.

Are you using a Swarm Coordinator with multiple Swarm agents on your network? If yes, can you post a screenshot of your Swarm settings? It looks like you’re just running with the default settings, i.e. the Swarm coordinator is still configured as RENDER-01, which is our coordinator here at Epic HQ. You need to change that name to the name of your computer that runs the Swarm Coordinator.

The certificate check failing is not really an error. You can ignore it.

If you are just using Swarm locally on your PC, i.e. no coordinator, then please go to the Settings and enable verbose logging so that we can get some more output. Post the logs here, thanks!

Hi Dissipation,

Please continue this conversation on this thread: Why is SwarmAgent crashing after failing to connect to Swarm? - Rendering - Unreal Engine Forums as the two reports are very similar and may have the same answer. Thank you!
