 VM restart - no access anymore (network) (3 Replies, Read 4143 times)

Good day

When I create a new VM, everything works (network, access to the VM etc.)

But when I restart the existing VM, I no longer have access (no access to the VM - via network).

Does anyone know this problem - possibly bug?

Thanks

Greetings Dave

Oudel.com provides the best full admin RDP, dedicated server, VPS & hosting at the best price.
Its maybe for your server network interface changed. You can create Network Bridge to avoid network problems.

Hello

I created the virtual machine and started it (br21)--> Works.

The virtual machine restarted (br21), no longer works.

Added or changed a new IP address to the virtual machine does not work either.
