I'm not sure if I'm doing something wrong or just this simply doesn't work.

So I have this error:
162856-create-bastion.jpg

My vnet address spaces:
162883-address-space.jpg

And my subnets:
162894-subnets.jpg

as far as I saw from all the tutorials it should be as simple as this. what's missing?

    Hello @Igor Meszaros ,

    Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

    As mentioned in the error and the official doc, the Bastion host is deployed in the virtual network that contains the AzureBastionSubnet subnet that has a minimum /26 prefix.

    Refer : https://video2.skills-academy.com/en-us/azure/bastion/tutorial-create-host-portal#prerequisites

    So, once you change the AzureBastionSubnet prefix to 10.4.0.0/26, it will work.

    Kindly let us know if the above helps or you need further assistance on this issue.
