I am experiencing following issue with EMS after numerous issues with IIS which recently broke down.
I was stuck with WinRM error and after consulting this guide I ended up with this: 

   New-PSSession : [server.domain.local] Connecting to remote server server.domain.local failed with  
    the following error message :  For more information, see the about_Remote_Troubleshooting Help topic.  
   At line:1 char:1  
   + New-PSSession -ConnectionURI "$connectionUri" -ConfigurationName Micr ...  
   + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
       + CategoryInfo          : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [New-PSSession], PSRemotin  
      gTransportException  
       + FullyQualifiedErrorId : -2144108173,PSSessionOpenFailed

We were able to fix the ECP but not toolbox and EMS.
The error message which seems to be empty, time to time spits some gibberish. For instance: 

   New-PSSession : [server.domain.local] Connecting to remote server [server.domain.local] failed with  
    the following error message :  欯ȍ For more information, see the about_Remote_Troubleshooting Help topic.  
   At line:1 char:1  
   + New-PSSession -ConnectionURI "$connectionUri" -ConfigurationName Micr ...  
   + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
       + CategoryInfo          : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [New-PSSession], PSRemotin  
      gTransportException  
       + FullyQualifiedErrorId : -2144108173,PSSessionOpenFailed

One time it was very long string of what seemed like XML config. But that one I scraped later on. (possible security issue?)
Regardless, the error search have not showed what else could be wrong. IIS bindings should be right but I will gladly get a second opinion on those should they be wrong as well.

OS is Windows server 2019 and IIS is v15.

Thank you in advance,
Kostas.

    @Kosta Moisidis

    I would suggest you try to connect to EMS from remote PowerShell. If you cannot connect to EMS with remote PowerShell, it mean the EMS virtual directory has broken, you could take steps below to recreate it:

    Run PowerShell with administrator privileges on your Exchange server, then import module below 

    Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn;

    You will could check EMS virtual directory with command below: 

    Get-PowerShellVirtualDirectory

    Then use commands below to delete EMS virtual directory and recreate it: 

    Remove-PowerShellVirtualDirectory -Identity "EXName\PowerShell (Default Web Site)" -Confirm:$false  
New-PowerShellVirtualDirectory -Server "EXName" -Name Powershell -InternalUrl https://EXName.domain.com/PowerShell -ExternalUrl https://mail.domain.com/PowerShell -RequireSSL:$false
