Title: Message Title

Toni Van de Voorde updated an issue   Jenkins / JENKINS-59137 Connectivity issues with ec2 slaves Change By: Toni Van de Voorde Hi guys, Since yesterday (28/08/19) we are facing a strange issue with our builds on jenkins. Either our builds are failing immediately, either the builds perform all steps but fail at the end. And each time it seems to be related with a connectivity issue with the slaves. I tried to figure out what the issue is but the it's too cryptic :/ The funny part is that I don't remember upgrading anything. So I did upgrade to latest version (jenkins and plugin) but the problem persists. Hopefully the following stacktraces tell you more.   This is a stacktrace I found in the jenkins log server: {code:java} 2019-08-29 06:28:05.986+0000 [id=257] WARNING
