I want to use remote powershell and invoke-command in a domain environment. For this, I made the necessary settings on both the client and host computers. However, when I want to run a simple command such as

invoke-command {whoami} -ComputerName HOST -Credential username

I get the error "Connecting to remote server HOST failed with the following error message: WS-Management cannot process the request. The operation failed because of an HTTP error." What could be the cause of the problem and possible solutions?

I tried manually enabling the Computer Configuration > Administrative Templates > Windows Components > Windows Remote Management settings and creating firewall inbound rules, but I did not get any results.
