Hello Team,

We have deployed machine agent as an  side car(different container within a pod) for  apache in OSE. It's working for most of the pod but for one pod we are getting below error.

We have cross-verified and everything looks good from the configuration end. 

Kindly help us with your suggestions.

@Ryan.Paredez  Thanks for your reply. I have gone thought all the post. They are mentioning about the incorrect configuration, could be possible reason of the error. The configuration look good from our side i.e. same config is working other PODS.

I have opened the support case and we are working on it.

Regards,

Hello Ryan,

The error was related to the stale connection. After clearing the  clearing the stale nodes from controller end it got resolved.
