I created a cluster on Microsoft Azure which created a Virtual Machine. Whenever I try to SSH into the Virtual Machine, I get a 'Connection timed out' error. I have tried restarting the Virtual Machine and I've also checked the Network Security Group to make sure port 22 is not blocked. The Network Security Group is not blocking traffic to port 22. Are there any suggestions for resolving the 'Connection timed out' error?
Hi,
Something here might help:
Troubleshoot SSH connections to an Azure Linux VM that fails, errors out, or is refused

Best regards,

Thanks Leon, I've tried the suggestions in the Troubleshoot SSH connections link that you sent. I'm still unable to SSH into the VM. If I create a VM that's not part of the cluster, I can SSH into it fine but not the one in the cluster.
Did you check the local firewalls of the Ubuntu machines?

Hello @Brittany-7193,
Could you please provide us the details of the cluster service you setup in Azure (like Service Fabric, Kubernetes etc.)
Thanks, Manu
Yes, I checked the local firewalls and reset the SSH configuration as well. I even restarted the VM and redeployed the VM.
Hey Manu,
It's a Kubernetes cluster with 1 Standard D8s v3 node on it.
Kubernetes cluster? The subject says Ubuntu, anyways check the following :

Hello @Brittany,
I suggest you to go with the following Easy way to SSH into Azure Kubernetes Service cluster node VMs (kubectl-plugin-ssh-jump)

Good day @Brittany ,
The following Microsoft official document provides step-by-step explanation on how to connect with SSH to Azure Kubernetes Service (AKS) cluster nodes
https://learn.microsoft.com/en-us/azure/aks/ssh
Note: I recommend to follow the tutorial and create new test machines. Once it is working well, go back to your real live VM and implement it. This way you will already have an understanding of the procedure and a working test.
