Error: No Listener Connected

Hi guys,
I have a recurrence flow to run a desktop flow. I connected using power automate machine runtime. I'm able to run in attended mode. but when I run in unattended mode it failed with error message: No Listener Connected. 
What could be wrong here? I'm not sure is it because it cannot log in to my computer account? cause I saw the machine credential in unattended mode is empty while in attended mode it has domain/username. When I login to my computer, I saw the website that I intended to extract the data with my desktop flow is opened but at the front or login page. and a small window with some error message which I did not screenshot. Can anyone help me to figure out what's wrong?
 
 
I received email report too:
 
 
I go to the link to check for more info. very technical. I think could be firewall or something blocking. so probably cannot run on unattended mode. Has anyone encountered this before and what is your solution?
 
 
 
I re-run again. I think it manage to connect and get the desktop flow running but somehow cannot find the element to click. This round can see machine credential is signed to my domain/username.
 
I think maybe has to do with the firewall or something
 
 
If anyone can find any solution to this can help me?

    @laclws Hi,
    Some steps you may want to check:
    1. Open the Machine Runtime on the machine, click troubleshoot,  then click launch  diagostic  tool.
     
     
     
    2. Reboot the machine.
     
    3. check this article if still has problem.
