This error indicates that VS Code for Web is unable to create the necessary Dev Tunnel session. Since the Cloud Shell is still running and the directories have not been recreated, the issue likely stems from the Azure server (either the Dev Tunnel service or the Cloud Shell provisioning process), rather than your local environment.
To resolve this, try switching to a different Cloud Shell region, restarting the Cloud Shell, or accessing VS Code Web directly at vscode.dev. If the problem continues across different devices and networks, it may be a region-specific service issue. In that case, please submit a support request so that Microsoft can review the Dev Tunnel logs for your tenant.
Hi, unfortunately the subscription is a VisualStudio offering and doesn't have tech support at all, I am using it to demo things during my learning-teaching sessions (I am an MCT).
It seems to be a back-end problem, I will try to reproduce problem when I will have some more time available, get the logs-traces and see if I can send them to MS support ! :)
Many thanks for you time though,
Regards, Panos

Did this start happening without you making any configuration changes, or was anything updated just before the issue started?
