I have an established machine connection from PAD as per the pic below:

When I go to said environment in cloud flows and try to use the Desktop Flow action, I can initially see the machine as a connection option but then quickly, after choosing it, I get an error connection message as per below::

Also, as per the Machines section Power Automate cloud, the machine is indeed connected:

And as can be seen in the action above, the machine's various desktop flows appear initially. When I try to enter my domain, username and password (PIN password), the connection cannot be re-established as per the pic below:

I've tried several times, checked that I'm using the correct credentials and nothing changes. While I get these connection errors, PAD states that the machine is indeed still connected to my environment (and the Machines section still state that the Machine is connected). Not sure if this is something that has to do with my computer password being a PIN type, but I have tried changing that on my setting and I haven't been able to (Windows 11).
What else could I try? Any help will be appreciated!! Thanks.
