The network is working before and I have not change anything on vm. After few months, I can not access the vm instance.
The vm instance is running
I will get "Request timed out" when ping to external network ip address.
I can not access SSH. The SSH port was open properly.
When troubleshooting my connection status of SSH in browser, it is stuck on Network status.
What should I do to know the reason of problem? After I restart the vm instance few times, it will running normally for a period, but the problem will appear again.
Any idea to make sure the vm instance will not disconnect from external network with this reason again?
Here are the resource consuming of my vm
In this case, VESTACP minimum system requirements for VM instances should be okay. But you can also consider the workload process for your VM instance.
I recommend switching to a higher N1 machine types to provide good performance for the workload and machine requirements.
