I'm hoping somebody can help. I have tried to setup Bastion in my subscription and am hitting the following error on any VM I try to connect to. When I try to connect it opens a new browser window with black screen and to in the lower right corner I get a dialogue box saying...
'The network connection to the Bastion Host appears unstable.'
Then a dialogue box saying...
'The connection has been closed because the target machine is taking too long to respond. This is usually caused by network problems, such as a spotty wireless signal, or slow network speeds. Please check your network connection and try again or contact your system administrator.'
Bastion appears to be setup correctly, has its own dedicated /27 subnet within the same vnet as the VM's I'm trying to connect to. There is no NSG applied on either the VM or on the Bastion subnet. Presumably if no NSG is applied there should be nothing internally within Azure blocking it. Yet I cannot seem to establish a connection to any of my VM's.
Worth a mention I tried looking this up before posting and seen some people mentioning they had set their RDP port to something other than 3389, and resetting this back fixed the issue. I have not changed the RDP port on any VM and confirmed all are still set to 3389.
Any help would be appreciated.
