Cannot launch jenkins slaves

Hi,

I am not able to launch slaves at all using the DigitalOcean Jenkins plugin… It goes like bootloop. Any advises on how to fix this?

This is what I see in the logs:

java.io.IOException: Agent failed to connect, even though the launcher didn't report it. See the log output for details.
