Container is not able to connect back to jenkins. By looking into it, I found that the config.sh is missing.
Is it something that I have to configure from my side. I have checked all the settings and configuration .

YAD plugin version - 0.2.0
Jenkins version - 2.308

PS: The same setup is working in another jenkins with version 2.249.2

no, file will be placed into container automatically and contain settings required for connection. If it's missing then something failed in start up process

How can I check where it went wrong, because the same setup is working on another jenkins master

everything should be in jenkins log
