I'm trying to access the VM via Bastion but I'm not able to connect it as I get connection time out error. Would it be any firewall issue? Any help is much appreciated.

    Hi @Vivekraj Md ,

    please check if you have Network Security Groups (NSGs) deployed and related/associated with the VM or the subnet the VM is connected with.

    In the NSG(s) you need to allow Port 3389 for RDP or/and Port 22 for SSH connections.

    Same counts for firewalls. If there are firewalls to control communication/connections your might need rules to allow the connections between Azure Bastion and the VM.

    Which Azure Bastion SKU Type are you using (Dev, or Basic)?
