Azure Web SSH prompt login window

Question

Azure Web SSH prompt login window

Ken Fly 46

When I follow https://learn.microsoft.com/en-us/azure/app-service/configure-linux-open-ssh-session#open-ssh-session-in-browser to open web ssh, the frontend prompts a window asking me for username and password to sign in.

I tried docker ssh username and password but it does not work.

I tried https://learn.microsoft.com/en-us/azure/app-service/configure-linux-open-ssh-session#open-ssh-session-from-remote-shell and have no issue to ssh from command line.

If you're not yet authenticated, you're required to authenticate with your Azure subscription to connect. Once authenticated, you see an in-browser shell, where you can run commands inside your container.

I am curious why some of my app services asking me for username and password when web ssh, some not.

They are all using the same docker image.

Where is the related config?

@Ken Fly Thank you for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this. yes all will be using the same

Connecting to SSH for Linux containers using either Web ssh method or Remote-shell method requires authentication, and you need to pass your azure subscription credentials.

Remote-shell method would have worked for you since you might have tried to SSH into Linux container of the app service through cloud shell from portal or command line editor from your local machine where you have already been authenticated already. In other words, refresh token is not expired from the last session.

Expected behavior is that the user will be prompted irrespective of the SSH method provided the refresh token is expired.

Feel free to reach back to me if you have any further questions on this.

I have accessed to several resource groups.

For some resource groups, I can access to web ssh without issue.
But for some resource groups, it keeps asking me for login info as below.

Since it always like that, no matter when I access to those web ssh.

I think it is something related to config?

Please correct me if I made a mistake. Thanks for your advice.

@Ken Fly Thanks for sharing more information on this. Based on the above shared screenshot looks like you are using custom authentication instead of Microsoft authentication. As mentioned earlier whatever the method you are using for SSH into linux azure web apps it will require authentication unless until if you have authenticated already or your refresh doesn't expired from the last session.

@VenkateshDodda-MSFT

I checked authentication tab of both app services, they are both blank.

We did not add anything to Authentication tab

As I mentioned earlier, all our app services use the same docker image.
Why some app service asks login info when using web ssh, some do not ask me for login info?

My refresh is not expired for sure. Since I can do everything else except cannot access to web ssh.

Even it asks me for login, I just cannot access to web ssh but can do all the rest operations normally

@Ken Fly Thanks for your response. This would need one on one offline support, for deeper investigations and might need to engage product team as well and I will suggest you open a support ticket.
