Virtual machine stopped suddenly and is not accessible again even when its status is running.

Hi,

I was working in my virtual machine; everything was working fine. Suddenly, it started trying to reconnect even there was no network interruption. I changed the network and also restarted the machine but, i was unable to access my VM.

I also tried to connect from different system but it was worthless. Later, i created a new VM about a week ago. But, today the same issue occurred with this VM also. I am unable to access it even when it is started from the portal.

Hello

Here are some troubleshooting steps that might help:

Reset Remote Desktop Configuration: This step resets the RDP configuration when Remote Connections are disabled or Windows Firewall rules are blocking RDP.

Check Network Security Group rules / Cloud Services endpoints: Ensure that the necessary ports are open and not being blocked by any firewall rules.

Review VM console logs: This can provide more information about what might be causing the issue.

Reset the NIC for the VM: This can sometimes resolve network-related issues.

Check the VM Resource Health: This can help identify any underlying issues with the VM.

Reset your VM password: This can help if there are issues with authentication.

Restart your VM: Sometimes, a simple restart can resolve the issue.

Redeploy your VM: If none of the above steps work, you might consider redeploying your VM.

Also, ensure that your host machine has a working network connection and that the virtual machine’s firewall is not blocking Internet access. If this virtual machine was converted from a physical system, verify that there are no hidden network adapters present.

If you’re still having trouble after trying these steps, you might consider reaching out to Azure support or VMware support, depending on the platform you’re using.

Hello, @Anurag Pandey ! It's odd that you've been able to connect to a VM and that stops working after a period of time on multiple VMs. That makes me wonder if the workload is either too much for the VM or if the VM state is becoming compromised (a hung task, for example). There are a lot of troubleshooting options, which I'll list below.

How do I troubleshoot scenarios where I can't connect to my VM?

I would second @Wesley Li and also recommend going through the VM troubleshooting guide for RDP connections:

https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/troubleshoot-rdp-connection

Quick troubleshooting steps After each troubleshooting step, try reconnecting to the VM:

Reset Remote Desktop configuration.

Check Network Security Group rules / Cloud Services endpoints.

Review VM console logs.

Reset the NIC for the VM.

Check the VM Resource Health.

Reset your VM password.

Restart your VM.

Redeploy your VM.

I would also look at your VM performance and analyze workloads to see if there is something that is causing your VM to hang. If you are still having issues after completing the troubleshooting, let us know in the comments as we may need to take a closer look at your resources.

I hope this has been helpful! Your feedback is important so please take a moment to accept answers.
