After we updated the plugin to version 1.30.0 the docker plugin keeps provisioning because it is unable to find the credentials for the docker containers.

```

ERROR: Launching agent process aborted. java.lang.InterruptedException: Validate configuration: The selected credentials cannot be found at hudson.plugins.sshslaves.SSHLauncher.checkConfig(SSHLauncher.java:900) at hudson.plugins.sshslaves.SSHLauncher.launch(SSHLauncher.java:402) at hudson.slaves.DelegatingComputerLauncher.launch(DelegatingComputerLauncher.java:64) at hudson.slaves.SlaveComputer$1.call(SlaveComputer.java:297) at jenkins.util.ContextResettingExecutorService$2.call(ContextResettingExecutorService.java:46) at jenkins.security.ImpersonatingExecutorService$2.call(ImpersonatingExecutorService.java:71) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
```
 
After downgrading back to version 1.28.1 everything seems to work again.
 
Changing the settings in the yet another docker plugin did not change anything.
Creating new credentials and selecting those didn't change anything either.

I also created an issue in github for this plugin because i do not know which one causes the problem (https://github.com/KostyaSha/yet-another-docker-plugin/issues/278)
