Hi,
Do you have any firewalls or any network configuration changes that could have occured recently impacted this? Can you can troubleshoot your connectivity issues by navigating to the Connection Troubleshoot tab (in the Monitoring section) of your Azure Bastion resource in the Azure portal. Network Watcher Connection Troubleshoot provides the capability to check a direct TCP connection from a virtual machine (VM) to a VM, fully qualified domain name (FQDN), URI, or IPv4 address.
