Why would an RDP connection to a VM fail with "Your credentials did not work"?

The new VM was created in the same subscription. The password doesn't work. All diagnostics ran OK.

To narrow the problem domain, the problem can be recreated consistently in Microsoft Learn DP-300 Lab exercise (Provision SQL virtual machine).

The lab starts in a labondemand.com "sandbox".

From within the sandbox, the VM is created under the user's subscription.

Problem 1: Connecting to that VM via RDP hangs on "initializing".

Problem 2: When connecting to that VM from outside the sandbox, results in "Credentials do not work".

See the attached screenshot.

Hello Andrew Brown

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

There could be several reasons why an RDP connection to a VM fails with "Your credentials did not work". Here are a few things you can check:

-Make sure you are using the correct username and password. If you are not sure, try resetting the password for the VM.

-Check if the VM is running. If the VM is not running, you won't be able to connect to it.

-Check if the VM is accessible from the internet. If the VM is not accessible from the internet, you won't be able to connect to it. You can check this by using this link (https://ping.eu/port-chk/).

-Check if the RDP port is open in the network security group (NSG) associated with the VM. By default, RDP uses port 3389. If the port is not open, you won't be able to connect to the VM.

-Check if the RDP service is running on the VM. If the RDP service is not running, you won't be able to connect to the VM.

If you have checked all of the above and still cannot connect to the VM, you can try resetting the RDP configuration on the VM.

Hope this helps.

A new error occurred this morning:

From within the sandbox, Azure portal login page would not connect due to an SSL error. The login worked after the page was refreshed.

Continuing the tutorial resulted in the same problem: the sandbox is unable to connect to the new VM. RDP failed on initializing.

The tutorial is the problem.

The tutorial says, "You will not be charged". I was charged.

From within the tutorial, the RDP connection fails to initialize.

Connecting through the public IP fails with "Your credentials did not work".

Something is wrong with the tutorial. I do not have a support contract. How to get someone to look at this?

I do not have a support contract. How to get someone's attention on the Microsoft Learn DP-300 Lab 1 tutorial?

Hello @Andrew Brown

There could be many reasons why credentials does not work. I would recommend to start with

Reset your RDP connection. This troubleshooting step resets the RDP configuration when Remote Connections are disabled or Windows Firewall rules are blocking RDP.
Reset user credentials. This troubleshooting step resets the password on a local administrator account when you are unsure or have forgotten the credentials. Once you have logged into the VM, you should reset the password for that user.

More troubleshooting steps could be found in below link

I think that I may be in a "hackers' container". Hackers are "front running" all my internet traffic and doing a deep copy of everything. I see the hackers' copy of the internet.

Please see my comment above.
