How to deal with error "dial tcp 10.240.0.4:10250: i/o timeout" to see pod's logs in AKS?
Not sure if your issue is caused by the problem described in this troubleshooting. But maybe you can take a try, it shows below:
Make sure that the default network security group isn't modified andthat both port 22 and 9000 are open for connection to the API server.Check whether the
