Answer 2

You may also check if admin user and password set in installation script is correct. I received this error due to incorrect credentials of admin user to connect to Sitecore.

Answer 3

Please refer to this blog article if it helps. Viet has noted down all the errors as well that he faced. Also, the error that you are facing is a part of the comments.

Quoting the solution from the blog:

You should ensure that your Sitecore Identity Server is up and running. If NO, perhaps you installed .Net Core incorrectly (have a look at Identity Server’s log and Event Viewer of Windows)

Answer 4

To fix this issue, I restarted the identity website and app pool... reset iis... then, resumed installation from the failed task - https://navansitecorenotes.blogspot.com/2020/05/getidservertoken-invoke-restmethod.html... Thanks
